1142252-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1142252-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,2,5 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1142252-68:
(9*1)+(8*1)+(7*4)+(6*2)+(5*2)+(4*5)+(3*2)+(2*6)+(1*8)=113
113 % 10 = 3
So 1142252-68-3 is a valid CAS Registry Number.
