77130-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77130-59-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,3 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77130-59:
(7*7)+(6*7)+(5*1)+(4*3)+(3*0)+(2*5)+(1*9)=127
127 % 10 = 7
So 77130-59-7 is a valid CAS Registry Number.

POTENTIAL ROUTES TO CYCLOBUTACYCLOPROPABENZENE
Hillard III, Russell L.,Vollhardt, K. Peter C.
, p. 2435 - 2440 (2007/10/02)
The CpCo(CO)2-catalyzed cyclization of 1-trimethylsilyl-1,5-hexadiyne (4) with propargyltetrahydropyranylether (5) leads to the formation of both possible regioisomers of the benzocyclobutene product: 3-trimethylsilyl-4-tetrahydropyranyloxymethylbenzocycl
