Check Digit Verification of cas no

The CAS Registry Mumber 403706-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,7,0 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 403706-60:
(8*4)+(7*0)+(6*3)+(5*7)+(4*0)+(3*6)+(2*6)+(1*0)=115
115 % 10 = 5
So 403706-60-5 is a valid CAS Registry Number.

High pressure-assisted low-loading asymmetric organocatalytic conjugate addition of nitroalkanes to chalcones

Cholewiak, Agnieszka,Adamczyk, Kamil,Kopyt, Micha?,Kasztelan, Adrian,Kwiatkowski, Piotr

, p. 4365 - 4371 (2018/06/22)

The application of high pressure (up to 9 kbar) allows for relatively fast (1-5 h) and highly enantioselective 1,4-addition of nitromethane and 2-nitropropane to chalcones at room temperature with substantial reduction of catalyst loading (0.2-1 mol% of cinchona alkaloid-based thioureas and squaramides). Various γ-nitroketones were obtained at 9 kbar with high yield and enantioselectivity (up to 98%), whereas in control experiments at atmospheric pressure usually only a small amount (10%) of products were formed after 20 h.
