Check Digit Verification of cas no

The CAS Registry Mumber 1402045-96-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,0,4 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1402045-96:
(9*1)+(8*4)+(7*0)+(6*2)+(5*0)+(4*4)+(3*5)+(2*9)+(1*6)=108
108 % 10 = 8
So 1402045-96-8 is a valid CAS Registry Number.

Modification and optimization of the bis-picolylamide-based relay protection for carboxylic acids to be cleaved by unusual complexation with Cu2+ salts

Mundinger, Stephan,Jakob, Uwe,Bichovski, Plamen,Bannwarth, Willi

, p. 8968 - 8979,12 (2012/12/11)

A simple modification of our recently published protection scheme for carboxylic acids as amides resulted in a new protecting group with significantly improved properties. It requires shorter reaction times for deprotection and allows us to replace Cu(OTf)2 by CuCl2, indicating at the same time the importance of the nature of the anion of the Cu2+ source. Since the new scheme fulfills all criteria required for an ideal protection group it should find widespread application in synthetic organic chemistry.
