72247-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72247-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,4 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72247-81:
(7*7)+(6*2)+(5*2)+(4*4)+(3*7)+(2*8)+(1*1)=125
125 % 10 = 5
So 72247-81-5 is a valid CAS Registry Number.
