1144112-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1144112-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,4,1,1 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1144112-67:
(9*1)+(8*1)+(7*4)+(6*4)+(5*1)+(4*1)+(3*2)+(2*6)+(1*7)=103
103 % 10 = 3
So 1144112-67-3 is a valid CAS Registry Number.
