Check Digit Verification of cas no

The CAS Registry Mumber 51814-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,1 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51814-47:
(7*5)+(6*1)+(5*8)+(4*1)+(3*4)+(2*4)+(1*7)=112
112 % 10 = 2
So 51814-47-2 is a valid CAS Registry Number.

A novel and efficient method for cleavage of phenacylesters by magnesium reduction with acetic acid

Kokinaki, Stella,Leondiadis, Leondios,Ferderigos, Nikolas

, p. 1723 - 1724 (2005)

(Equation Presented) In the present study, we use magnesium turnings as a new deprotection reagent for the phenacyl group during orthogonal organic synthesis in the presence of other esters and sensitive protecting groups. By applying the new magnesium turnings/acetic acid deprotection method, phenacyl group can be more easily combined with other protecting groups that are not compatible with the zinc/acetic acid method.
