Check Digit Verification of cas no
The CAS Registry Mumber 344346-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,3,4 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 344346-68:
(8*3)+(7*4)+(6*4)+(5*3)+(4*4)+(3*6)+(2*6)+(1*8)=145
145 % 10 = 5
So 344346-68-5 is a valid CAS Registry Number.
