402476-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 402476-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,4,7 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 402476-20:
(8*4)+(7*0)+(6*2)+(5*4)+(4*7)+(3*6)+(2*2)+(1*0)=114
114 % 10 = 4
So 402476-20-4 is a valid CAS Registry Number.

Reactions of iodinated vinylidene complexes generated from 1-Iodo-1-alkynes and W(CO)5(thf)

, p. 518 - 519 (2007/10/03)
We have succeeded in generating iodinated tungsten vinylidene complexes from 1-iodo-1-alkynes and W(CO)5(thf), and have employed these complexes for two types of synthetically useful reactions, that is, 6π-electrocyclization for o-(iodoethynyl)
