99620-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99620-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99620-40:
(7*9)+(6*9)+(5*6)+(4*2)+(3*0)+(2*4)+(1*0)=163
163 % 10 = 3
So 99620-40-3 is a valid CAS Registry Number.
