99699-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99699-11-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,9 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99699-11:
(7*9)+(6*9)+(5*6)+(4*9)+(3*9)+(2*1)+(1*1)=213
213 % 10 = 3
So 99699-11-3 is a valid CAS Registry Number.
