Check Digit Verification of cas no

The CAS Registry Mumber 1669-12-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1669-12:
(6*1)+(5*6)+(4*6)+(3*9)+(2*1)+(1*2)=91
91 % 10 = 1
So 1669-12-1 is a valid CAS Registry Number.
