99809-90-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99809-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99809-90:
(7*9)+(6*9)+(5*8)+(4*0)+(3*9)+(2*9)+(1*0)=202
202 % 10 = 2
So 99809-90-2 is a valid CAS Registry Number.
