Check Digit Verification of cas no

The CAS Registry Mumber 1303516-21-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,3,5,1 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1303516-21:
(9*1)+(8*3)+(7*0)+(6*3)+(5*5)+(4*1)+(3*6)+(2*2)+(1*1)=103
103 % 10 = 3
So 1303516-21-3 is a valid CAS Registry Number.

On the synthesis of conformationally modified peptides through isonitrile chemistry: Implications for dealing with polypeptide aggregation

Wu, Xiangyang,Park, Peter K.,Danishefsky, Samuel J.

, p. 7700 - 7703 (2011/07/31)

A method for introducing a dimethyleneoxy constraint joining the N atoms of two consecutive amino acids in the context of a polypeptide has been developed. This constraint can profoundly affect the tendency of a polypeptide to suffer aggregation and desolubilization, and it can be readily removed under mild conditions.
