Check Digit Verification of cas no

The CAS Registry Mumber 1449701-55-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,7,0 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1449701-55:
(9*1)+(8*4)+(7*4)+(6*9)+(5*7)+(4*0)+(3*1)+(2*5)+(1*5)=176
176 % 10 = 6
So 1449701-55-6 is a valid CAS Registry Number.

Efficient synthesis of indene derivatives by cascade reactions

-

Paragraph 0053; 0054, (2017/01/09)

The present invention relates to an efficient synthesis method of indene derivatives through cascade reaction. In the present invention, a novel one-pot cascade approach to the synthesis of 1H-indene-3-carboxamides and 1H-indene-3-carboxylate derivatives through thermolysis of a diazo compound is developed. Along with various aromatic and heteroaromatic aldehydes, aliphatic or aromatic primary amine and aliphatic alcohol or phenol derivative are used as nucleophilic components. In the present invention, a multicomponent reaction without using a catalyst enables the synthesis of variously functionalized indene derivatives, and can be widely applied to the synthesis of natural products and medicine.
