Check Digit Verification of cas no

The CAS Registry Mumber 142672-74-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,7 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142672-74:
(8*1)+(7*4)+(6*2)+(5*6)+(4*7)+(3*2)+(2*7)+(1*4)=130
130 % 10 = 0
So 142672-74-0 is a valid CAS Registry Number.
