Check Digit Verification of cas no

The CAS Registry Mumber 142055-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,5 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142055-06:
(8*1)+(7*4)+(6*2)+(5*0)+(4*5)+(3*5)+(2*0)+(1*6)=89
89 % 10 = 9
So 142055-06-9 is a valid CAS Registry Number.

Intermolecular reactions of N-alkoxycarbonyliminium ions with propargyltrimethylsilane; oxazinone versus allene formation

Esch,Hiemstra,Speckamp

, p. 3445 - 3462 (2007/10/02)

Intermolecular reactions of N-alkoxycarbonyliminium ions with propargyltrimethylsilane mainly lead to 6-(trimethylsilyl)methyl-3,4-dihydro-2H-1,3-oxazinones, formed by intramolecular trapping of a stabilized β-sily vinylic cation. α-Allenyl carbamates are obtained as minor products. The oxazinone/allene ratio is dependent on the nature of the Lewis acid and the solvent used.
