Check Digit Verification of cas no

The CAS Registry Mumber 78666-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,6 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78666-78:
(7*7)+(6*8)+(5*6)+(4*6)+(3*6)+(2*7)+(1*8)=191
191 % 10 = 1
So 78666-78-1 is a valid CAS Registry Number.
