111534-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111534-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,5,3 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111534-91:
(8*1)+(7*1)+(6*1)+(5*5)+(4*3)+(3*4)+(2*9)+(1*1)=89
89 % 10 = 9
So 111534-91-9 is a valid CAS Registry Number.
