99564-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99564-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,6 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 99564-04:
(7*9)+(6*9)+(5*5)+(4*6)+(3*4)+(2*0)+(1*4)=182
182 % 10 = 2
So 99564-04-2 is a valid CAS Registry Number.
