475662-10-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 475662-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,6,6 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 475662-10:
(8*4)+(7*7)+(6*5)+(5*6)+(4*6)+(3*2)+(2*1)+(1*0)=173
173 % 10 = 3
So 475662-10-3 is a valid CAS Registry Number.
