111940-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111940-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,4 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111940-35:
(8*1)+(7*1)+(6*1)+(5*9)+(4*4)+(3*0)+(2*3)+(1*5)=93
93 % 10 = 3
So 111940-35-3 is a valid CAS Registry Number.
