Check Digit Verification of cas no

The CAS Registry Mumber 80760-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,7,6 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80760-64:
(7*8)+(6*0)+(5*7)+(4*6)+(3*0)+(2*6)+(1*4)=131
131 % 10 = 1
So 80760-64-1 is a valid CAS Registry Number.

4-Methoxy-2,6-dimethylbenzenesulphonyl (Mds): a New Protecting Group of the Guanidino Function in Peptide Synthesis

Fujino, Masahiko,Nishimura, Osamu,Wakimasu, Mitsuhiro,Kitada, Chieko

, p. 668 - 669 (1980)

The 4-methoxy-2,6-dimethylbenzenesulphonyl (Mds) group for the protection of the guanidino function, which is readily removed with trifluoroacetic acid-thioanisole but is resistant to hydrogenolysis or treatment with dilute hydrogen chloride, can be used in the solution synthesis of arginine-containing peptides; this protecting group was effectively used in the synthesis of substance P and two LH-RH analogues.
