1111685-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1111685-20-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,6,8 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1111685-20:
(9*1)+(8*1)+(7*1)+(6*1)+(5*6)+(4*8)+(3*5)+(2*2)+(1*0)=111
111 % 10 = 1
So 1111685-20-1 is a valid CAS Registry Number.
