Check Digit Verification of cas no

The CAS Registry Mumber 21953-79-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,5 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21953-79:
(7*2)+(6*1)+(5*9)+(4*5)+(3*3)+(2*7)+(1*9)=117
117 % 10 = 7
So 21953-79-7 is a valid CAS Registry Number.
