Check Digit Verification of cas no

The CAS Registry Mumber 1089311-11-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,3,1 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1089311-11:
(9*1)+(8*0)+(7*8)+(6*9)+(5*3)+(4*1)+(3*1)+(2*1)+(1*1)=144
144 % 10 = 4
So 1089311-11-4 is a valid CAS Registry Number.

Transition-metal-free synthesis of (E)-vinyl sulfones from vinyl halides in water

Liang, Shuai,Zhang, Ruo-Yi,Wang, Gao,Chen, Shan-Yong,Yu, Xiao-Qi

supporting information, p. 7050 - 7053 (2013/11/06)

A practical transition-metal-free procedure for the synthesis of (E)-vinyl sulfones through the coupling of vinyl halides with sodium sulfinates in water is reported. The reaction is strongly influenced by the presence of acids, and the use of nBu4NBr promotes its efficiency.
