Check Digit Verification of cas no

The CAS Registry Mumber 150367-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,3,6 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 150367-14:
(8*1)+(7*5)+(6*0)+(5*3)+(4*6)+(3*7)+(2*1)+(1*4)=109
109 % 10 = 9
So 150367-14-9 is a valid CAS Registry Number.

A General Method for the Preparation of 2,2-Disubstituted 1-Nitroalkenes

Denmark, Scott E.,Marcin, Lawrence R.

, p. 3850 - 3856 (1993)

A general and expeditious route for the preparation of functionalized 2,2-disubstituted 1-nitroalkenes has been developed.Conjugate 1,4-addition of complex zinc cuprates (RCu(CN)ZnI) to easily obtained (E)-1-nitroalkenes, followed by trapping with phenylselenenyl bromide and subsequent oxidative elimination, afforded the corresponding 2,2-disubstituted 1-nitroalkenes in good yields. 2-Alkyl-2-aryl- and 2,2-dialkyl nitroalkenes 4b-g were prepared in 76-88percent yield and obtained as E/Z isomeric mixtures, slightly favoring the Z isomer (ca. 1.0:1.5, E/Z).
