Check Digit Verification of cas no

The CAS Registry Mumber 1374229-55-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,2,2 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1374229-55:
(9*1)+(8*3)+(7*7)+(6*4)+(5*2)+(4*2)+(3*9)+(2*5)+(1*5)=166
166 % 10 = 6
So 1374229-55-6 is a valid CAS Registry Number.

Synthesis of tetrasubstituted NH pyrroles and polysubstituted furans via an addition and cyclization strategy

Li, Liang,Zhao, Mi-Na,Ren, Zhi-Hui,Li, Jianli,Guan, Zheng-Hui

experimental part, p. 532 - 540 (2012/04/04)

The FeCl3-catalyzed addition and cyclization of enamino esters with nitroolefins provides a straightforward and general method for the synthesis of tetrasubstituted NH pyrroles. This novel method tolerates a wide range of functionality, and allows for rapid elaboration of the nitroolefins into a variety of substituted pyrroles in good yields. Further, an efficient KOAc-promoted addition and cyclization protocol toward substituted furans has been described as well. Georg Thieme Verlag Stuttgart · New York.
