Check Digit Verification of cas no

The CAS Registry Mumber 1449477-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,4,7 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1449477-99:
(9*1)+(8*4)+(7*4)+(6*9)+(5*4)+(4*7)+(3*7)+(2*9)+(1*9)=219
219 % 10 = 9
So 1449477-99-9 is a valid CAS Registry Number.

Green synthesis of new boron-containing quinazolines: Preparation of benzo[d][1,3,2]diazaborinin-4(1H)-one derivatives

, p. 2936 - 2942 (2013/09/02)

A series of new boron-containing quinazolinones, benzo[d][1,3,2] diazaborinin-4(1H)-one derivatives, were synthesized by the sequential one-pot reaction of isatoic anhydride, amines, and arylboronic acids in the absence of a catalyst and solvent. Heating isotoic anhydride and amines led to the formation of 2-aminobenzamide intermediates, which reacted easily with boronic acids to obtain the title compounds in good yields. Solvent-free conditions provided a unique procedure because the corresponding products were not obtained using various solvents either under reflux conditions or at room temperature.
