106112-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106112-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,1,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 106112-05:
(8*1)+(7*0)+(6*6)+(5*1)+(4*1)+(3*2)+(2*0)+(1*5)=64
64 % 10 = 4
So 106112-05-4 is a valid CAS Registry Number.
