Check Digit Verification of cas no

The CAS Registry Mumber 3929-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,2 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3929-65:
(6*3)+(5*9)+(4*2)+(3*9)+(2*6)+(1*5)=115
115 % 10 = 5
So 3929-65-5 is a valid CAS Registry Number.
