432040-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 432040-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,2,0,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 432040-87:
(8*4)+(7*3)+(6*2)+(5*0)+(4*4)+(3*0)+(2*8)+(1*7)=104
104 % 10 = 4
So 432040-87-4 is a valid CAS Registry Number.
