74731-73-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74731-73-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,3 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74731-73:
(7*7)+(6*4)+(5*7)+(4*3)+(3*1)+(2*7)+(1*3)=140
140 % 10 = 0
So 74731-73-0 is a valid CAS Registry Number.
