180138-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180138-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,1,3 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 180138-12:
(8*1)+(7*8)+(6*0)+(5*1)+(4*3)+(3*8)+(2*1)+(1*2)=109
109 % 10 = 9
So 180138-12-9 is a valid CAS Registry Number.

Palladium catalysed [4+2]-cycloaddition reactions of (2-iodoaryl)allenes
Grigg, Ronald,Xu, Long-He
, p. 4251 - 4254 (2007/10/03)
(2-Iodoaryl)allenes are versatile 4C-components in palladium catalysed [4+2] cycloaddition reactions with norbornene, 2-aza-3-oxonorborn-5-ene, and allene acting as 2C-components. A variety of dihydronaphthalenes and naphthalenes are produced in excellent yield.
