Check Digit Verification of cas no

The CAS Registry Mumber 39968-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39968-91:
(7*3)+(6*9)+(5*9)+(4*6)+(3*8)+(2*9)+(1*1)=187
187 % 10 = 7
So 39968-91-7 is a valid CAS Registry Number.
