Check Digit Verification of cas no

The CAS Registry Mumber 916756-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,7,5 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 916756-03:
(8*9)+(7*1)+(6*6)+(5*7)+(4*5)+(3*6)+(2*0)+(1*3)=191
191 % 10 = 1
So 916756-03-1 is a valid CAS Registry Number.
