Check Digit Verification of cas no

The CAS Registry Mumber 77889-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,8 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77889-21:
(7*7)+(6*7)+(5*8)+(4*8)+(3*9)+(2*2)+(1*1)=195
195 % 10 = 5
So 77889-21-5 is a valid CAS Registry Number.

Nucleophilic Addition to 4,5-Dihydroimidazoles: A Ketone Synthesis via Tetrahydrofolate Coenzyme Models

Anderson, Michael W.,Jones, Raymond C.F.

, p. 1995 - 1998 (2007/10/02)

1-Benzyl-2-alkyl-3-methyl-4,5-dihydroimidazolium salts with Grignard reagents give addition products that are hydrolysed to ketones; 4,5-dihydroimidazoles and 4,5-dihydroimidazolium salts with hydride reagents afford N-alkylated ethane-1,2-diamines.

Dihydroimidazoles in Synthesis: C-Alkylation of 1-Benzyl-2-(α-lithioalkyl)-4,5-dihydroimidazoles and a Synthesis of Alkanoic Acids

Anderson, Michael W.,Jones, Raymond C. F.,Saunders, John

, p. 205 - 210 (2007/10/02)

1-Benzyl-2-alkyl-4,5-dihydroimidazoles have been (laterally) metallated and C-alkylated by reaction with alkyl halides and an epoxide; intramolecular C-alkylation has led to a tetrahydro-5H-pyrroloimidazole.Hydrolysis of the 4,5-dihydroimidazoles to produce alkanoic acids completes a homologation sequence.
