1159192-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159192-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,1,9 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1159192-41:
(9*1)+(8*1)+(7*5)+(6*9)+(5*1)+(4*9)+(3*2)+(2*4)+(1*1)=162
162 % 10 = 2
So 1159192-41-2 is a valid CAS Registry Number.
