Check Digit Verification of cas no

The CAS Registry Mumber 34711-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,1 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34711-50:
(7*3)+(6*4)+(5*7)+(4*1)+(3*1)+(2*5)+(1*0)=97
97 % 10 = 7
So 34711-50-7 is a valid CAS Registry Number.
