Check Digit Verification of cas no

The CAS Registry Mumber 4735-10-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,3 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4735-10:
(6*4)+(5*7)+(4*3)+(3*5)+(2*1)+(1*0)=88
88 % 10 = 8
So 4735-10-8 is a valid CAS Registry Number.
