Check Digit Verification of cas no
The CAS Registry Mumber 34515-82-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,5,1 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34515-82:
(7*3)+(6*4)+(5*5)+(4*1)+(3*5)+(2*8)+(1*2)=107
107 % 10 = 7
So 34515-82-7 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
