Check Digit Verification of cas no

The CAS Registry Mumber 920285-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,0,2,8 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 920285-74:
(8*9)+(7*2)+(6*0)+(5*2)+(4*8)+(3*5)+(2*7)+(1*4)=161
161 % 10 = 1
So 920285-74-1 is a valid CAS Registry Number.

Aluminum triflate as a powerful catalyst for direct amination of alcohols, including electron-withdrawing group-substituted benzhydrols

Ohshima, Takashi,Ipposhi, Junji,Nakahara, Yasuhito,Shibuya, Ryozo,Mashima, Kazushi

supporting information, p. 2447 - 2452 (2012/11/07)

Direct aminations of allylic alcohols, benzylic alcohols, and benzhydrols with electron-withdrawing (F, Br, I, NO2, or CN) substituents were efficiently catalyzed by aluminum triflate [Al(OTf)3] to afford the corresponding biarylamines in high yield, and the dibromo-substituted product was further transformed into letrozole.

Intermolecular hydroamination of allenes with N-unsubstituted carbamates catalyzed by a gold(I) N-heterocyclic carbene complex

Kinder, Robert E.,Zhang, Zhibin,Widenhoefer, Ross A.

supporting information; experimental part, p. 3157 - 3159 (2009/05/11)

(Chemical Equation Presented) Reaction of 2,3-pentadienyl benzoate with benzyl carbamate catalyzed by a 1:1 mixture of (NHC)AuCl and AgOTf in dioxane at 23°C for 5 h led to isolation of (E)-4-(benzyloxycarbonylamino)-2-pentenyl benzoate in 84% yield as a single regio- and diastereomer. Gold(I)-catalyzed hydroamination was effective for a number of N-unsubstituted carbamates and a range of substituted allenes.
