1142252-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1142252-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,2,5 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1142252-91:
(9*1)+(8*1)+(7*4)+(6*2)+(5*2)+(4*5)+(3*2)+(2*9)+(1*1)=112
112 % 10 = 2
So 1142252-91-2 is a valid CAS Registry Number.
