6938-30-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6938-30-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6938-30:
(6*6)+(5*9)+(4*3)+(3*8)+(2*3)+(1*0)=123
123 % 10 = 3
So 6938-30-3 is a valid CAS Registry Number.
