Check Digit Verification of cas no

The CAS Registry Mumber 1252644-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,6,4 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1252644-41:
(9*1)+(8*2)+(7*5)+(6*2)+(5*6)+(4*4)+(3*4)+(2*4)+(1*1)=139
139 % 10 = 9
So 1252644-41-9 is a valid CAS Registry Number.

1,3-Difunctionalization of β-alkyl nitroalkenes via combination of Lewis base catalysis and radical oxidation

Wang, Ye,Zheng, Lei,Shi, Xiaodong,Chen, Yunfeng

, p. 886 - 889 (2021)

Upon treatment with a Lewis base catalyst, β-alkyl-substituted nitroalkenes could be readily converted into allylic nitro compounds. Examples of either C-1 or C-3 functionalization methods have been reported through nitro-elimination, giving alkene products. In this work, successful 1,3-difunctionalization was achieved through a synergetic Lewis base catalysis and TBHP radical oxidation, giving vinylic alkoxyamines in good to excellent yields. This work further extended the general synthetic application of β-alkyl nitroalkenes.
