Check Digit Verification of cas no

The CAS Registry Mumber 76337-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,3 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76337-12:
(7*7)+(6*6)+(5*3)+(4*3)+(3*7)+(2*1)+(1*2)=137
137 % 10 = 7
So 76337-12-7 is a valid CAS Registry Number.
