Check Digit Verification of cas no

The CAS Registry Mumber 140847-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,4 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140847-76:
(8*1)+(7*4)+(6*0)+(5*8)+(4*4)+(3*7)+(2*7)+(1*6)=133
133 % 10 = 3
So 140847-76-3 is a valid CAS Registry Number.
