1027021-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027021-93-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,0,2 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027021-93:
(9*1)+(8*0)+(7*2)+(6*7)+(5*0)+(4*2)+(3*1)+(2*9)+(1*3)=97
97 % 10 = 7
So 1027021-93-7 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 (2003)
(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
