478189-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 478189-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,1,8 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 478189-43:
(8*4)+(7*7)+(6*8)+(5*1)+(4*8)+(3*9)+(2*4)+(1*3)=204
204 % 10 = 4
So 478189-43-4 is a valid CAS Registry Number.
