2974-73-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2974-73-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2974-73:
(6*2)+(5*9)+(4*7)+(3*4)+(2*7)+(1*3)=114
114 % 10 = 4
So 2974-73-4 is a valid CAS Registry Number.
