330824-97-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 330824-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,8,2 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 330824-97:
(8*3)+(7*3)+(6*0)+(5*8)+(4*2)+(3*4)+(2*9)+(1*7)=130
130 % 10 = 0
So 330824-97-0 is a valid CAS Registry Number.

Palladium(0)-catalyzed carbonylation-coupling-cyclization of allenic sulfonamides with aryl iodides and carbon monoxide
Kang, Suk-Ku,Kim, Kwang-Jin
, p. 511 - 514 (2001)
(Matrix presented) α-Allenic sulfonamides undergo carbonylation-coupling-endo-cyclization with aryl iodides in the presence of Pd(PPh3)4 (5 mol %), K2CO3, and CO (20 atm) to form 3-aroyl-2- or 3-pyrrolines. Alte
