183005-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183005-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,0,0 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 183005-99:
(8*1)+(7*8)+(6*3)+(5*0)+(4*0)+(3*5)+(2*9)+(1*9)=124
124 % 10 = 4
So 183005-99-4 is a valid CAS Registry Number.

Radical cyclization of α-allenic ketone: A new approach to the synthesis of (±)-α-chamigrene
Chen, Yao-Jung,Wang, Chi-Ying,Lin, Wen-Yuan
, p. 13181 - 13188 (2007/10/03)
A regioselective cyclization of ε-alkyl radicals attacking on the sp-carbon of α-allenic ketone to construct a spiro[5.5]undecane skeleton has been studied, and a new approach to the synthesis of (±)-α-chamigrene 22 is also reported.
