72731-78-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72731-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,3 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 72731-78:
(7*7)+(6*2)+(5*7)+(4*3)+(3*1)+(2*7)+(1*8)=133
133 % 10 = 3
So 72731-78-3 is a valid CAS Registry Number.
