Check Digit Verification of cas no

The CAS Registry Mumber 423771-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,3,7,7 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 423771-31:
(8*4)+(7*2)+(6*3)+(5*7)+(4*7)+(3*1)+(2*3)+(1*1)=137
137 % 10 = 7
So 423771-31-7 is a valid CAS Registry Number.

, p. 3498 - 3499 (2002)

The phosphotriesterase from Pseudomonas diminuta has been shown to selectively cleave the pro-R p-nitrophenolate substituent from bis-p-nitrophenyl alkyl phosphothioate esters. When the alkyl substituent is methyl, ethyl, or isopropyl the enantiomeric exc
