Check Digit Verification of cas no

The CAS Registry Mumber 674309-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,4,3,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 674309-76:
(8*6)+(7*7)+(6*4)+(5*3)+(4*0)+(3*9)+(2*7)+(1*6)=183
183 % 10 = 3
So 674309-76-3 is a valid CAS Registry Number.
