Check Digit Verification of cas no

The CAS Registry Mumber 157224-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,2,2 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157224-41:
(8*1)+(7*5)+(6*7)+(5*2)+(4*2)+(3*4)+(2*4)+(1*1)=124
124 % 10 = 4
So 157224-41-4 is a valid CAS Registry Number.

An efficient synthesis of aryl phenaceturates using acid catalyzed dicyclohexylcarbodiimide esterification and transient N-tert-butoxycarbonylation

Cabaret,Liu,Wakselman

, p. 480 - 482 (2007/10/02)

Application of the Holmberg procedure (DCC/pyridine/p-TSA(cat)) improves the yield of the direct condensation of phenols with phenylacetylglycine (1). Moreover, N-tert-butoxycarbonylation of 1 impedes an intramolecular reaction leading to an oxazolone, an
