99702-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99702-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,0 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99702-47:
(7*9)+(6*9)+(5*7)+(4*0)+(3*2)+(2*4)+(1*7)=173
173 % 10 = 3
So 99702-47-3 is a valid CAS Registry Number.
