Check Digit Verification of cas no

The CAS Registry Mumber 2990-12-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2990-12:
(6*2)+(5*9)+(4*9)+(3*0)+(2*1)+(1*2)=97
97 % 10 = 7
So 2990-12-7 is a valid CAS Registry Number.
