Check Digit Verification of cas no

The CAS Registry Mumber 305819-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,5,8,1 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 305819-40:
(8*3)+(7*0)+(6*5)+(5*8)+(4*1)+(3*9)+(2*4)+(1*0)=133
133 % 10 = 3
So 305819-40-3 is a valid CAS Registry Number.

A photochemical approach to phenylalanines and related compounds by alkylation of glycine

Knowles, Haydn S.,Hunt, Keith,Parsons, Andrew F.

, p. 8115 - 8124 (2007/10/03)

Phenylalanines can be prepared on UV photolysis of protected glycines in the presence of di-tert-butyl peroxide, substituted toluenes and the photosensitiser benzophenone. These reactions, which lead to highly selective mono-alkylation at the α-position of glycines, involve coupling of captodative α-glycine radicals with benzyl radicals. This method can be used to selectively alkylate a variety of glycine derivatives using a range of substituted toluenes under neutral reaction conditions.
