2613-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2613-74-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,1 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 2613-74:
(6*2)+(5*6)+(4*1)+(3*3)+(2*7)+(1*4)=73
73 % 10 = 3
So 2613-74-3 is a valid CAS Registry Number.
