Check Digit Verification of cas no

The CAS Registry Mumber 130490-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,4,9 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130490-17:
(8*1)+(7*3)+(6*0)+(5*4)+(4*9)+(3*0)+(2*1)+(1*7)=94
94 % 10 = 4
So 130490-17-4 is a valid CAS Registry Number.

EFFICIENT CONVERSION OF 1-ARYL-3,3-DIALKYLTRIAZENES TO PHENOLS AND OXYGEN-18 LABELED PHENOLS

Satyamurthy, N.,Barrio, Jorge R.,Bida, Gerald T.,Phelps, Michael E.

, p. 4409 - 4412 (1990)

Phenols have been synthesized in excellent yields using a cation exchange resin (H+ form) assisted decomposition of 1-aryl-3,3-dialkyltriazenes in the presence of water.This method is also amenable to a high yield and high enrichment synthesis of oxygen-17 and 18 labeled phenols.
