99818-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99818-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,1 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99818-73:
(7*9)+(6*9)+(5*8)+(4*1)+(3*8)+(2*7)+(1*3)=202
202 % 10 = 2
So 99818-73-2 is a valid CAS Registry Number.
