128266-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128266-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,6 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128266-89:
(8*1)+(7*2)+(6*8)+(5*2)+(4*6)+(3*6)+(2*8)+(1*9)=147
147 % 10 = 7
So 128266-89-7 is a valid CAS Registry Number.
