128651-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128651-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,5 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128651-43:
(8*1)+(7*2)+(6*8)+(5*6)+(4*5)+(3*1)+(2*4)+(1*3)=134
134 % 10 = 4
So 128651-43-4 is a valid CAS Registry Number.
