Check Digit Verification of cas no

The CAS Registry Mumber 216568-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,5,6 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 216568-80:
(8*2)+(7*1)+(6*6)+(5*5)+(4*6)+(3*8)+(2*8)+(1*0)=148
148 % 10 = 8
So 216568-80-8 is a valid CAS Registry Number.

6-N-(N-methylanthranylamido)-4-oxo-hexanoic acid : A new fluorescent protecting group applicable to a new DNA sequencing method

Rasolonjatovo, Isabelle,Sarfati, Simon R.

, p. 2021 - 2025 (2007/10/03)

6-Amino-4-oxo-hexanoic acid with a fluorescent probe attached to the amino function, derivative of the levulinic acid has been developed for protection of hydroxyl groups. It is introduced by reaction of its symetrical anhydride and rapidly removed under mild conditions using a hydrazine- pyridinium acetate buffer at near neutral pH and room temperature. It can be used within the scope of a new DNA sequencing method and as a sensitive detectable protecting group.
