Check Digit Verification of cas no

The CAS Registry Mumber 3295-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,9 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3295-58:
(6*3)+(5*2)+(4*9)+(3*5)+(2*5)+(1*8)=97
97 % 10 = 7
So 3295-58-7 is a valid CAS Registry Number.
