402475-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 402475-94-9 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 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 402475-94:
(8*4)+(7*0)+(6*2)+(5*4)+(4*7)+(3*5)+(2*9)+(1*4)=129
129 % 10 = 9
So 402475-94-9 is a valid CAS Registry Number.

Reactions of iodinated vinylidene complexes generated from 1-Iodo-1-alkynes and W(CO)5(thf)
Miura, Tomoya,Iwasawa, Nobuharu
, p. 518 - 519 (2002)
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)
