144192-17-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144192-17-6 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, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144192-17:
(8*1)+(7*4)+(6*4)+(5*1)+(4*9)+(3*2)+(2*1)+(1*7)=116
116 % 10 = 6
So 144192-17-6 is a valid CAS Registry Number.
