Check Digit Verification of cas no

The CAS Registry Mumber 1041850-07-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,1,8,5 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1041850-07:
(9*1)+(8*0)+(7*4)+(6*1)+(5*8)+(4*5)+(3*0)+(2*0)+(1*7)=110
110 % 10 = 0
So 1041850-07-0 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.
