Check Digit Verification of cas no

The CAS Registry Mumber 31059-79-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,5 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31059-79:
(7*3)+(6*1)+(5*0)+(4*5)+(3*9)+(2*7)+(1*9)=97
97 % 10 = 7
So 31059-79-7 is a valid CAS Registry Number.
