Check Digit Verification of cas no

The CAS Registry Mumber 4707-29-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4707-29:
(6*4)+(5*7)+(4*0)+(3*7)+(2*2)+(1*9)=93
93 % 10 = 3
So 4707-29-3 is a valid CAS Registry Number.
