Check Digit Verification of cas no

The CAS Registry Mumber 2901-02-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2901-02:
(6*2)+(5*9)+(4*0)+(3*1)+(2*0)+(1*2)=62
62 % 10 = 2
So 2901-02-2 is a valid CAS Registry Number.
