72293-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72293-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,9 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72293-65:
(7*7)+(6*2)+(5*2)+(4*9)+(3*3)+(2*6)+(1*5)=133
133 % 10 = 3
So 72293-65-3 is a valid CAS Registry Number.
