Check Digit Verification of cas no

The CAS Registry Mumber 15224-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,2 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15224-05:
(7*1)+(6*5)+(5*2)+(4*2)+(3*4)+(2*0)+(1*5)=72
72 % 10 = 2
So 15224-05-2 is a valid CAS Registry Number.

Synthesis of Unsymmetrical Functionalised Organic Sulphides

Singh, Harjit,Batra, Manohar S.,Singh, Paramjit

, p. 131 - 136 (2007/10/02)

Acyclic thioiminium salts and the condensed thiazolium salts in the presence of aqueous sodium hydroxide as such or under base catalyzed phase transfer catalysis conditions react with appropiate organic halides to provide corresponding unsymmetrical functionalized organic sulphides.With aqueous sodium hydroxide, thioiminium salts provide the disulphides corresponding to incipient thiol.
