Check Digit Verification of cas no

The CAS Registry Mumber 53939-30-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,3 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53939-30:
(7*5)+(6*3)+(5*9)+(4*3)+(3*9)+(2*3)+(1*0)=143
143 % 10 = 3
So 53939-30-3 is a valid CAS Registry Number.

Site-Selectivity in the Reaction of 3-Substituted Pyridine 1-Oxides with Phosphoryl Chloride

Yamanaka, Hiroshi,Araki, Tomio,Sakamoto, Takao

, p. 2244 - 2247 (2007/10/02)

Site-selectivity in the reaction of 3-substituted pyridine 1-oxide with phosphoryl chloride was investigated.When a strongly electron-withdrawing group (e.g.CN, CONRR', COOR, or NO2) was substituted at the 3-position, the reaction of 3-substituted pyridine 1-oxides with phosphoryl chloride yielded 3-substituted 2-chloropyridines as the main products.Keywords- site-selectivity; 3-substituted pyridine 1-oxide; phosphoryl chloride; 3-substituted 2-chloropyridine; chlorination
