Check Digit Verification of cas no

The CAS Registry Mumber 221012-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,1 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 221012-44:
(8*2)+(7*2)+(6*1)+(5*0)+(4*1)+(3*2)+(2*4)+(1*4)=58
58 % 10 = 8
So 221012-44-8 is a valid CAS Registry Number.

A novel thiol protecting group: A 2-thioquinoline sulfide as a masked sulfhydryl moiety

Zhang, Jiancun,Matteucci, Mark D.

, p. 1467 - 1470 (2007/10/03)

2-Thioquinoline sulfide was developed as a masked sulfhydryl entity. It is introduced through facile S(N)2 displacement reactions and is stable to a variety of reaction conditions including acids, bases and nucleophiles. It is readily unmasked using the mild treatment of sodium cyanoborohydride in acetic acid.
