Check Digit Verification of cas no

The CAS Registry Mumber 95927-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,9,2 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 95927-64:
(7*9)+(6*5)+(5*9)+(4*2)+(3*7)+(2*6)+(1*4)=183
183 % 10 = 3
So 95927-64-3 is a valid CAS Registry Number.

Phosphorus Pentoxide in Organic Synthesis, XII - Synthesis of 7H-Pyrrolopyrimidin-4-amines

Jorgensen, Anker,Girgis, Nabih S.,Pedersen, Erik B.

, p. 142 - 148 (2007/10/02)

A one-step synthesis for the preparation of a new series of substituted 7H-pyrrolopyrimidin-4-amines 2 is described.The method consists in heating the corresponding pyrrolopyrimidin-4(3H)-ones 1 in a mixture of phosphorus pentoxide, N,N-dimethylcyclohexylamine, and the appropriate amine hydrochloride.With aromatic amine hydrochlorides the reaction proceeds smoothly at 200 - 220 deg C for 1-4 h, whereas with aliphatic amine hydrochlorides, the reaction takes place at slower rate affording the products 3 in lower yields.With diethylamine hydrochloride, the condensed dimeric product 5 is isolated together with the expected product 3e.The results from pesticide screenings are reported.
