744142-42-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 744142-42-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,4,1,4 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 744142-42:
(8*7)+(7*4)+(6*4)+(5*1)+(4*4)+(3*2)+(2*4)+(1*2)=145
145 % 10 = 5
So 744142-42-5 is a valid CAS Registry Number.
