62653-83-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62653-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,5 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62653-83:
(7*6)+(6*2)+(5*6)+(4*5)+(3*3)+(2*8)+(1*3)=132
132 % 10 = 2
So 62653-83-2 is a valid CAS Registry Number.
