128007-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128007-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,0 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128007-45:
(8*1)+(7*2)+(6*8)+(5*0)+(4*0)+(3*7)+(2*4)+(1*5)=104
104 % 10 = 4
So 128007-45-4 is a valid CAS Registry Number.
