Check Digit Verification of cas no

The CAS Registry Mumber 2345-29-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,4 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2345-29:
(6*2)+(5*3)+(4*4)+(3*5)+(2*2)+(1*9)=71
71 % 10 = 1
So 2345-29-1 is a valid CAS Registry Number.

Mild method for the selective esterification of carboxylic acids based on the Garegg-samuelsson reaction

Morcillo, Sara P.,Alvarez De Cienfuegos, Luis,Mota, Antonio J.,Justicia, Jose,Robles, Rafael

experimental part, p. 2277 - 2281 (2011/05/19)

A mild method for the selective esterification of primary alcohols is described. The use of different phosphines, I2, and imidazole allows the selective esterification of a wide variety of acids with excellent results. The generation of a bulky phosphonium-carboxylate salt as intermediate could justify the selectivity observed in this process. Additionally, amides also can be synthesized with use of this method.
