475558-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 475558-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,5,5 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 475558-31:
(8*4)+(7*7)+(6*5)+(5*5)+(4*5)+(3*8)+(2*3)+(1*1)=187
187 % 10 = 7
So 475558-31-7 is a valid CAS Registry Number.
