1027402-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027402-28-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,4,0 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1027402-28:
(9*1)+(8*0)+(7*2)+(6*7)+(5*4)+(4*0)+(3*2)+(2*2)+(1*8)=103
103 % 10 = 3
So 1027402-28-3 is a valid CAS Registry Number.

Iodine-Catalyzed Direct C-H Alkenylation of Azaheterocycle N-Oxides with Alkenes
Zhang, Zhenhao,Pi, Chao,Tong, Heng,Cui, Xiuling,Wu, Yangjie
, p. 440 - 443 (2017)
An efficient and regioselective alkenylation of azaheterocycle N-oxides with alkenes catalyzed by iodine under metal- and external oxidant-free reaction conditions has been developed. A variety of (E)-2-styrylazaheterocycles have been produced in moderate
