99030-27-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99030-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,3 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99030-27:
(7*9)+(6*9)+(5*0)+(4*3)+(3*0)+(2*2)+(1*7)=140
140 % 10 = 0
So 99030-27-0 is a valid CAS Registry Number.

Radical Annulation: A Method for Preparation of Carbocycles
Angoh, Gaeatan A.,Clive, Derrick L. J.
, p. 980 - 982 (2007/10/02)
β-Acetylenic radicals, e.g., (6b) and (12), generated in three steps from epoxides or in two steps from α-halogenoketones, respectively, react with electron-defficient olefins to produce five-membered carbocycles by a process of conjugate addition and 5-e
