Check Digit Verification of cas no

The CAS Registry Mumber 1231958-85-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,1,9,5 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1231958-85:
(9*1)+(8*2)+(7*3)+(6*1)+(5*9)+(4*5)+(3*8)+(2*8)+(1*5)=162
162 % 10 = 2
So 1231958-85-2 is a valid CAS Registry Number.

Synthesis of Nα-Z protected amino alkyl triazole acids and their application to neo-glycopeptides synthesis

Madhu, Chilakapati,Panguluri, Nageswara Rao,Sureshbabu, Vommina V.

, p. 858 - 864 (2014/08/05)

The synthesis of triazole linked glycopeptides employing 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) mediated coupling of Z-protected triazole acids with glycosyl amines and amino acid esters is described. The coupling proceeded smoothly at room temperat

A simple synthesis of N β-Fmoc/Z-amino alkyl thiols and their use in the synthesis of N β-Fmoc/Z-amino alkyl sulfonic acids

Sureshbabu,Vishwanatha,Vasantha

body text, p. 1037 - 1042 (2010/07/06)

A simple and efficient protocol for the synthesis of Nβ- Fmoc/Z-amino alkyl thiols is described. The approach uses sodium pyrosulfite-mediated hydrolysis of isothiouronium salts resulting from the reaction between N-protected aminoalkyl iodides and thiourea. N-Protected taurines were prepared through performic acid oxidation of the thiols and the products were further utilized for the synthesis of dipeptidosulfonamides.
