Check Digit Verification of cas no

The CAS Registry Mumber 33554-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,5,5 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33554-90:
(7*3)+(6*3)+(5*5)+(4*5)+(3*4)+(2*9)+(1*0)=114
114 % 10 = 4
So 33554-90-4 is a valid CAS Registry Number.

Iodine monobromide catalysed regioselective synthesis of 3-arylquinolines from α-aminoacetophenones and: Trans -β-nitrostyrenes

Gattu, Radhakrishna,Mondal, Santa,Ali, Saghir,Khan, Abu T.

, p. 347 - 353 (2019)

A simple and efficient method for regioselective synthesis of 3-arylquinolines is described from α-aminoacetophenones and trans-β-nitrostyrenes using 20 mol% iodine monobromide as a catalyst in acetonitrile solvent at 80 °C. The present method involves tandem reaction of α-aminoacetophenones and trans-β-nitrostyrenes, formation of two new C-C bonds and cleavage of one C-C bond in a single step. The salient features of the protocol are metal- and oxidant-free reaction conditions, broad substrate scope, and good yields.
