Check Digit Verification of cas no

The CAS Registry Mumber 1916-74-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,1 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1916-74:
(6*1)+(5*9)+(4*1)+(3*6)+(2*7)+(1*4)=91
91 % 10 = 1
So 1916-74-1 is a valid CAS Registry Number.
