267888-50-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 267888-50-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,7,8,8 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 267888-50:
(8*2)+(7*6)+(6*7)+(5*8)+(4*8)+(3*8)+(2*5)+(1*0)=206
206 % 10 = 6
So 267888-50-6 is a valid CAS Registry Number.

En route to archimedene: Total synthesis of C3h-symmetric [7]phenylene
Bruns, Dirk,Miura, Hirokazu,Vollhardt, K. Peter C.,Stanger, Amnon
, p. 549 - 552 (2007/10/03)
(Matrix presented) The total synthesis of C3h-symmetric [7]phenylene has been accomplished by triple cobalt-catalyzed cycloisomerization of an appropriate nonayne. Its spectral data are in accord with the expectations for a triply angularly fus
