111012-41-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111012-41-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,0,1 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111012-41:
(8*1)+(7*1)+(6*1)+(5*0)+(4*1)+(3*2)+(2*4)+(1*1)=40
40 % 10 = 0
So 111012-41-0 is a valid CAS Registry Number.
