144192-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144192-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,9 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144192-34:
(8*1)+(7*4)+(6*4)+(5*1)+(4*9)+(3*2)+(2*3)+(1*4)=117
117 % 10 = 7
So 144192-34-7 is a valid CAS Registry Number.
