Check Digit Verification of cas no

The CAS Registry Mumber 51953-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,5 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51953-62:
(7*5)+(6*1)+(5*9)+(4*5)+(3*3)+(2*6)+(1*2)=129
129 % 10 = 9
So 51953-62-9 is a valid CAS Registry Number.
