1119195-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1119195-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,9,1,9 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1119195-41:
(9*1)+(8*1)+(7*1)+(6*9)+(5*1)+(4*9)+(3*5)+(2*4)+(1*1)=143
143 % 10 = 3
So 1119195-41-3 is a valid CAS Registry Number.
