1142174-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1142174-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,1,7 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1142174-07:
(9*1)+(8*1)+(7*4)+(6*2)+(5*1)+(4*7)+(3*4)+(2*0)+(1*7)=109
109 % 10 = 9
So 1142174-07-9 is a valid CAS Registry Number.
