172607-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172607-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,6,0 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 172607-55:
(8*1)+(7*7)+(6*2)+(5*6)+(4*0)+(3*7)+(2*5)+(1*5)=135
135 % 10 = 5
So 172607-55-5 is a valid CAS Registry Number.

INTRAMOLECULAR CYCLIZATION OF ENYNE CUMULENALS
Garcia, J. Gabriel,Ramos, Bethzaida,Pratt, Lawrence M.,Rodriguez, Augusto
, p. 7391 - 7394 (2007/10/02)
Enyne cumulenals have been shown to undergo a Bergman cyclization or an intramolecular cycloaddition depending on the nature of substituents on the yne carbon.A hydrogen substituted cumulenal is cleanly converted to a naphthalene product while
