72397-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72397-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,9 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72397-80:
(7*7)+(6*2)+(5*3)+(4*9)+(3*7)+(2*8)+(1*0)=149
149 % 10 = 9
So 72397-80-9 is a valid CAS Registry Number.
