1159494-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159494-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,4,9 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1159494-41:
(9*1)+(8*1)+(7*5)+(6*9)+(5*4)+(4*9)+(3*4)+(2*4)+(1*1)=183
183 % 10 = 3
So 1159494-41-3 is a valid CAS Registry Number.
