Check Digit Verification of cas no

The CAS Registry Mumber 1007117-29-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,7,1,1 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1007117-29:
(9*1)+(8*0)+(7*0)+(6*7)+(5*1)+(4*1)+(3*7)+(2*2)+(1*9)=94
94 % 10 = 4
So 1007117-29-4 is a valid CAS Registry Number.

Synthesis of polysubstituted N-H pyrroles from vinyl azides and 1,3-dicarbonyl compounds

Chiba, Shunsuke,Wang, Yi-Feng,Lapointe, Guillaume,Narasaka, Koichi

, p. 313 - 316 (2008/09/19)

(Chemical Equation Presented) Two synthetic methods for tetra- and trisubstituted N-H pyrroles are presented: (i) the thermal pyrrole formation by the reaction of vinyl azides with 1,3-dicarbonyl compounds via the 1,2-addition of 1,3-dicarbonyl compounds to 2H-azirine intermediates generated in situ from vinyl azides; (ii) the Cu(II)-catalyzed synthesis of pyrroles from α-ethoxycarbonyl vinyl azides and ethyl acetoacetate through the 1,4-addition reaction of the acetoacetate to the vinyl azides. By applying these two methods, regioisomeric pyrroles can be prepared selectively starting from the same vinyl azides.
