Check Digit Verification of cas no

The CAS Registry Mumber 3151-21-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,5 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3151-21:
(6*3)+(5*1)+(4*5)+(3*1)+(2*2)+(1*1)=51
51 % 10 = 1
So 3151-21-1 is a valid CAS Registry Number.
