1344028-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1344028-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,4,0,2 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1344028-49:
(9*1)+(8*3)+(7*4)+(6*4)+(5*0)+(4*2)+(3*8)+(2*4)+(1*9)=134
134 % 10 = 4
So 1344028-49-4 is a valid CAS Registry Number.
