143468-62-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143468-62-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,6 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143468-62:
(8*1)+(7*4)+(6*3)+(5*4)+(4*6)+(3*8)+(2*6)+(1*2)=136
136 % 10 = 6
So 143468-62-6 is a valid CAS Registry Number.
