Check Digit Verification of cas no

The CAS Registry Mumber 67977-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,7 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67977-81:
(7*6)+(6*7)+(5*9)+(4*7)+(3*7)+(2*8)+(1*1)=195
195 % 10 = 5
So 67977-81-5 is a valid CAS Registry Number.
