Check Digit Verification of cas no

The CAS Registry Mumber 2669-83-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,6 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2669-83:
(6*2)+(5*6)+(4*6)+(3*9)+(2*8)+(1*3)=112
112 % 10 = 2
So 2669-83-2 is a valid CAS Registry Number.
