109164-86-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109164-86-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,6 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109164-86:
(8*1)+(7*0)+(6*9)+(5*1)+(4*6)+(3*4)+(2*8)+(1*6)=125
125 % 10 = 5
So 109164-86-5 is a valid CAS Registry Number.
