1854-83-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1854-83-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1854-83:
(6*1)+(5*8)+(4*5)+(3*4)+(2*8)+(1*3)=97
97 % 10 = 7
So 1854-83-7 is a valid CAS Registry Number.

, p. 9865 - 9875 (2013)

A pair of easily accessible vinyl sulfones derived from styrene epoxide and monotosylated glycerol were reacted with six different azidopyranosides having an azido group at C1, C2, C3, C4, C6, and at the terminal position of an exocylic chain attached to

An efficient one-pot, three-component synthesis of vinyl sulfones via iodide-catalyzed radical alkenylation

Fan, Weizheng,Su, Jiapeng,Shi, Dongyang,Feng, Bainian

, p. 6740 - 6743 (2015/08/24)

An efficient one-pot, three-component synthesis of vinyl sulfones via iodide-catalyzed radical alkenylation using aryl diazonium salts, terminal alkenes and DABSO is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive control experiments, we propose a plausible radical mechanism.
