Check Digit Verification of cas no

The CAS Registry Mumber 67641-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,4 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67641-12:
(7*6)+(6*7)+(5*6)+(4*4)+(3*1)+(2*1)+(1*2)=137
137 % 10 = 7
So 67641-12-7 is a valid CAS Registry Number.
