Check Digit Verification of cas no

The CAS Registry Mumber 113534-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,3 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113534-28:
(8*1)+(7*1)+(6*3)+(5*5)+(4*3)+(3*4)+(2*2)+(1*8)=94
94 % 10 = 4
So 113534-28-4 is a valid CAS Registry Number.

Esters of N-(9-Fluorenylmethoxycarbonyl) Amino Acids with 4-Hydroxy-3-oxo-2,5-diphenyl-2,3-dihydrothiophene 1,1-Dioxide (Fmoc-Amino Acid TDO Esters) and Their Use in Solid Phase Peptide Synthesis

Kirstgen, Reinhard,Olbrich, Alfred,Rehwinkel, Hartmut,Steglich, Wolfgang

, p. 437 - 440 (2007/10/02)

Fmoc-Amino acid TDO esters 3 are prepared by reaction of Fmoc-amino acids 1 with the cyclic carbonate 2.Their application in peptide synthesis is demonstrated by the preparation of leucylalanylvalylglycine (7) at a p-alkoxybenzyl alcohol resin.
