Check Digit Verification of cas no

The CAS Registry Mumber 1031685-74-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,6,8 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1031685-74:
(9*1)+(8*0)+(7*3)+(6*1)+(5*6)+(4*8)+(3*5)+(2*7)+(1*4)=131
131 % 10 = 1
So 1031685-74-1 is a valid CAS Registry Number.

Phenyl-EDOTn derivatives as super acid labile carboxylic acid protecting groups for peptide synthesis

Isidro-Llobet, Albert,álvarez, Mercedes,Albericio, Fernando

, p. 3304 - 3307 (2008/09/21)

A series of new 3,4-ethylenedioxy-2-thenyl (EDOTn) derived alcohols have been synthesized and evaluated as super acid labile carboxylic acid protecting groups. All the derivatives are labile to very low concentrations of TFA (0.01-0.5%).
