Check Digit Verification of cas no

The CAS Registry Mumber 74923-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,2 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74923-21:
(7*7)+(6*4)+(5*9)+(4*2)+(3*3)+(2*2)+(1*1)=140
140 % 10 = 0
So 74923-21-0 is a valid CAS Registry Number.
