99702-68-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99702-68-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,0 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99702-68:
(7*9)+(6*9)+(5*7)+(4*0)+(3*2)+(2*6)+(1*8)=178
178 % 10 = 8
So 99702-68-8 is a valid CAS Registry Number.
