Check Digit Verification of cas no

The CAS Registry Mumber 78647-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,4 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78647-40:
(7*7)+(6*8)+(5*6)+(4*4)+(3*7)+(2*4)+(1*0)=172
172 % 10 = 2
So 78647-40-2 is a valid CAS Registry Number.
