128862-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128862-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,6 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128862-99:
(8*1)+(7*2)+(6*8)+(5*8)+(4*6)+(3*2)+(2*9)+(1*9)=167
167 % 10 = 7
So 128862-99-7 is a valid CAS Registry Number.
