475207-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 475207-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,2,0 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 475207-81:
(8*4)+(7*7)+(6*5)+(5*2)+(4*0)+(3*7)+(2*8)+(1*1)=159
159 % 10 = 9
So 475207-81-9 is a valid CAS Registry Number.
