Check Digit Verification of cas no

The CAS Registry Mumber 55842-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,4 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55842-44:
(7*5)+(6*5)+(5*8)+(4*4)+(3*2)+(2*4)+(1*4)=139
139 % 10 = 9
So 55842-44-9 is a valid CAS Registry Number.

PTSA catalyzed straightforward protocol for the synthesis of 2-(N-acyl)aminobenzimidazoles and 2-(N-acyl)aminobenzothiazoles in PEG

Vidavalur, Siddaiah,Gajula, Mahaboob Basha,Tadikonda, Ramu,Nakka, Mangarao,Dega, Sudhakar,Yadav, Santosh Kumar,Voosala, Christopher

supporting information, p. 2691 - 2694 (2014/05/06)

An efficient PTSA catalyzed synthesis of 2-(N-acyl)aminobenzimidazoles and 2-(N-acyl)aminobenzothiazoles has been described using S-ethylated-N- acylthioureas as substrates and polyethylene glycol as solvent.

Phosphonium-mediated cyclization of N-(2-aminophenyl)thioureas: Efficient synthesis of 2-aminobenzimidazoles

Wan, Zhao-Kui,Ousman, Erena Farah,Papaioannou, Nikolaos,Saiah, Eddine

supporting information; experimental part, p. 4149 - 4152 (2011/09/19)

BOP efficiently promoted the phosphonium-mediated cyclization of thioureas, leading to a convenient synthesis of 2-aminobenzimidazoles. Compared to conventional methods, the reactions were complete at room temperature with times ranging from a few minutes

SYNTHESIS OF 4-ARYL BENZIMIDAZOLO-s-TRIAZIN-2-ONES AND 2-AROYLAMINOBENZIMIDAZOLO-1,2,4-THIADIAZOLINES

Sridevi, G.,Rao, P. Jayaprasad,Reddy, K. Kondal

, p. 965 - 972 (2007/10/02)

Reaction of 2-aminobenzimidazole with aroylisothiocyanates gave 2-aroylaminobenzimidazoles (3) and N-aroyl-N'-(benzimidazol-2-yl)-thioureas (4).The products obtained on reaction of 4 with PCl5 in POCl3 , and with oxidising agents have been identified as 4

SYNTHESIS OF 2-ARYL-1H-s-TRIAZOLOBENZIMIDAZOLES

Rao, P. Jayaprasad,Reddy, K. Kondal

, p. 1995 - 2002 (2007/10/02)

2-Aroylaminobenzimidazoles (2) have been converted into 1(2-benzimidazolyl)-5-aryl-1H-tetrazoles (4) by treatment with PCl5 followed by azidation with NaN3 in aqueous acetone solution.Pyrolysis of 4 in diphenylether yielded 2-aryl-1H-s-triazolobenzimidazoles (6).The product of benzylation of 6a has been characterised.A reasonable pathway for the formation of 6 from 4 has been suggested.
