Check Digit Verification of cas no

The CAS Registry Mumber 920833-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,0,8,3 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 920833-92:
(8*9)+(7*2)+(6*0)+(5*8)+(4*3)+(3*3)+(2*9)+(1*2)=167
167 % 10 = 7
So 920833-92-7 is a valid CAS Registry Number.

Chlorotrimethylsilane mediated synthesis of 5-(2hydroxybenzoyl)pyrimidines from 3-formylchromones

Ryabukhin, Sergey V.,Plaskon, Andrey S.,Volochnyuk, Dmitriy M.,Pipko, Sergey E.,Tolmachev, Andrey A.

, p. 583 - 597 (2008)

The recyclization of 3-formylchromones with a variety of 1,3-NCNbinucleophiles promoted by chlorotrimethylsilane was investigated. A simple and flexible general procedure for the synthesis of series of 5-(2hydroxybenzoyl)pyrimidines and their heterofused analogues was proposed. A set of pyrimidines was obtained in high preparative yields.
