99538-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99538-55-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,3 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99538-55:
(7*9)+(6*9)+(5*5)+(4*3)+(3*8)+(2*5)+(1*5)=193
193 % 10 = 3
So 99538-55-3 is a valid CAS Registry Number.
