Check Digit Verification of cas no

The CAS Registry Mumber 1627186-23-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,7,1,8 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1627186-23:
(9*1)+(8*6)+(7*2)+(6*7)+(5*1)+(4*8)+(3*6)+(2*2)+(1*3)=175
175 % 10 = 5
So 1627186-23-5 is a valid CAS Registry Number.

An efficient synthesis of pyrrolo[1,2-a]quinazoline derivatives in ionic liquid catalyzed by iodine

Lu, Lian,Yang, Ke,Zhang, Mei-Mei,Wang, Xiang-Shan

, p. 841 - 845 (2014/06/10)

A mild, green, and facile method for the synthesis of 2,3,3a,4- tetrahydropyrrolo[1,2-a]quinazoline-1,5-dione derivatives is described in high yields by using ionic liquids as green media. The method involves the reaction of 2-aminobenzamides with 4-oxopentanoic acid or 4-aryl-4-oxo-butanoic acid catalyzed by iodine and has the advantages of mild reaction conditions, high yields, one-pot, operational simplicity, and environmentally benign.
