66967-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66967-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,6 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66967-41:
(7*6)+(6*6)+(5*9)+(4*6)+(3*7)+(2*4)+(1*1)=177
177 % 10 = 7
So 66967-41-7 is a valid CAS Registry Number.

Simple and stereoselective synthetic route to (E)-1-alkenyl sulfoxides via terminal alkynes
Zhong,Guo,Huang
, p. 588 - 589 (2007/10/03)
Terminal alkynes 1 react with Cp2Zr(H)Cl (Cp = η5-C5H5) to give organozirconium (IV) complexes 2, which are trapped with sulfuryl chloride to afford (E)-1-alkenyl sulfoxides 3.
