Check Digit Verification of cas no

The CAS Registry Mumber 68451-74-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,5 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 68451-74:
(7*6)+(6*8)+(5*4)+(4*5)+(3*1)+(2*7)+(1*4)=151
151 % 10 = 1
So 68451-74-1 is a valid CAS Registry Number.
