99272-88-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99272-88-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,7 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99272-88:
(7*9)+(6*9)+(5*2)+(4*7)+(3*2)+(2*8)+(1*8)=185
185 % 10 = 5
So 99272-88-5 is a valid CAS Registry Number.
