Check Digit Verification of cas no

The CAS Registry Mumber 142389-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142389-71:
(8*1)+(7*4)+(6*2)+(5*3)+(4*8)+(3*9)+(2*7)+(1*1)=137
137 % 10 = 7
So 142389-71-7 is a valid CAS Registry Number.

Synthesis of cycloalkanone-fused cyclopropanes by Au(I)-catalyzed oxidative ene-yne cyclizations

Uetake, Yuta,Niwa, Takashi,Nakada, Masahisa

, p. 6847 - 6850 (2015/01/09)

Au(I)-catalyzed oxidative cyclizations that successfully convert 1,5-ene-ynes and a 1,6-ene-yne to the corresponding cycloalkanone-fused cyclopropanes are described. This Au(I)-catalyzed oxidative cyclization can be effectively applied to various substrat
