Check Digit Verification of cas no

The CAS Registry Mumber 82177-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,7 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82177-01:
(7*8)+(6*2)+(5*1)+(4*7)+(3*7)+(2*0)+(1*1)=123
123 % 10 = 3
So 82177-01-3 is a valid CAS Registry Number.

ACTIVATION OF CONVENTIONAL S-PROTECTING GROUPS OF CYSTEINE BY CONVERSION INTO THE 3-NITRO-2-PYRIDINESULFENYL (NPYS) GROUP

Matsueda, Rei,Higashida, Susumu,Ridge, Richard J.,Matsueda, Gary R.

, p. 921 - 924 (1982)

All the conventional S-protecting groups of cysteine which were tested could be selectively converted to the 3-nitro-2-pyridine-sulfenyl (Npys) group after treatment with an appropriate Npys halide.Unidirectional formation of an unsymmetrical disulfide bond is possible when Cys(Npys) is mixed with a free thiol of another Cys residue.Some of these features were exploited during the solid phase synthesis of lysine8-vasopressin.
