85175-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85175-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,7 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85175-26:
(7*8)+(6*5)+(5*1)+(4*7)+(3*5)+(2*2)+(1*6)=144
144 % 10 = 4
So 85175-26-4 is a valid CAS Registry Number.
