Check Digit Verification of cas no

The CAS Registry Mumber 640271-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,7 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 640271-56:
(8*6)+(7*4)+(6*0)+(5*2)+(4*7)+(3*1)+(2*5)+(1*6)=133
133 % 10 = 3
So 640271-56-3 is a valid CAS Registry Number.
