743393-86-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 743393-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,3,3,9 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 743393-86:
(8*7)+(7*4)+(6*3)+(5*3)+(4*9)+(3*3)+(2*8)+(1*6)=184
184 % 10 = 4
So 743393-86-4 is a valid CAS Registry Number.
