Check Digit Verification of cas no

The CAS Registry Mumber 135762-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,6 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135762-59:
(8*1)+(7*3)+(6*5)+(5*7)+(4*6)+(3*2)+(2*5)+(1*9)=143
143 % 10 = 3
So 135762-59-3 is a valid CAS Registry Number.
