Check Digit Verification of cas no

The CAS Registry Mumber 1251-99-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1251-99:
(6*1)+(5*2)+(4*5)+(3*1)+(2*9)+(1*9)=66
66 % 10 = 6
So 1251-99-6 is a valid CAS Registry Number.
