Check Digit Verification of cas no

The CAS Registry Mumber 97653-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,5 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 97653-12:
(7*9)+(6*7)+(5*6)+(4*5)+(3*3)+(2*1)+(1*2)=168
168 % 10 = 8
So 97653-12-8 is a valid CAS Registry Number.
