72139-66-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72139-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,3 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 72139-66:
(7*7)+(6*2)+(5*1)+(4*3)+(3*9)+(2*6)+(1*6)=123
123 % 10 = 3
So 72139-66-3 is a valid CAS Registry Number.
