Check Digit Verification of cas no

The CAS Registry Mumber 20433-63-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,3 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20433-63:
(7*2)+(6*0)+(5*4)+(4*3)+(3*3)+(2*6)+(1*3)=70
70 % 10 = 0
So 20433-63-0 is a valid CAS Registry Number.

Catalytic decomposition of simulants for chemical warfare V agents: Highly efficient catalysis of the methanolysis of phosphonothioate esters

Melnychuk, Stephanie A.,Neverov, Alexei A.,Brown, R. Stan

, p. 1767 - 1770 (2007/10/03)

(Chemical Equation Presented) As good as the original: Extremely effective methanolysis of phosphonothioates using metal-containing systems (e.g., 1) was achieved. The catalytic methanolysis of a SCH2CH2NEt 2 derivative, an analogue of the organophosphorus chemical warfare material VX, was predicted, and the catalyzed methanolysis of S-(3,5-dichlorophenyl) O-ethyl methylphosphonothioate was shown to involve a concerted displacement of the aryl thioate (transition state 2)
