105661-80-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105661-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,6,6 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 105661-80:
(8*1)+(7*0)+(6*5)+(5*6)+(4*6)+(3*1)+(2*8)+(1*0)=111
111 % 10 = 1
So 105661-80-1 is a valid CAS Registry Number.
