1621-47-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1621-47-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1621-47:
(6*1)+(5*6)+(4*2)+(3*1)+(2*4)+(1*7)=62
62 % 10 = 2
So 1621-47-2 is a valid CAS Registry Number.
