99639-10-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99639-10-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,3 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99639-10:
(7*9)+(6*9)+(5*6)+(4*3)+(3*9)+(2*1)+(1*0)=188
188 % 10 = 8
So 99639-10-8 is a valid CAS Registry Number.
