99333-79-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99333-79-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,3 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 99333-79:
(7*9)+(6*9)+(5*3)+(4*3)+(3*3)+(2*7)+(1*9)=176
176 % 10 = 6
So 99333-79-6 is a valid CAS Registry Number.
