72444-62-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72444-62-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,4 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72444-62:
(7*7)+(6*2)+(5*4)+(4*4)+(3*4)+(2*6)+(1*2)=123
123 % 10 = 3
So 72444-62-3 is a valid CAS Registry Number.
