143359-26-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143359-26-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,5 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143359-26:
(8*1)+(7*4)+(6*3)+(5*3)+(4*5)+(3*9)+(2*2)+(1*6)=126
126 % 10 = 6
So 143359-26-6 is a valid CAS Registry Number.
