Check Digit Verification of cas no

The CAS Registry Mumber 6156-14-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,5 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6156-14:
(6*6)+(5*1)+(4*5)+(3*6)+(2*1)+(1*4)=85
85 % 10 = 5
So 6156-14-5 is a valid CAS Registry Number.
