Check Digit Verification of cas no
The CAS Registry Mumber 343228-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,2,2 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 343228-68:
(8*3)+(7*4)+(6*3)+(5*2)+(4*2)+(3*8)+(2*6)+(1*8)=132
132 % 10 = 2
So 343228-68-2 is a valid CAS Registry Number.
