3908-72-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3908-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,0 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3908-72:
(6*3)+(5*9)+(4*0)+(3*8)+(2*7)+(1*2)=103
103 % 10 = 3
So 3908-72-3 is a valid CAS Registry Number.
