Check Digit Verification of cas no

The CAS Registry Mumber 1235581-11-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,5,8 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1235581-11:
(9*1)+(8*2)+(7*3)+(6*5)+(5*5)+(4*8)+(3*1)+(2*1)+(1*1)=139
139 % 10 = 9
So 1235581-11-9 is a valid CAS Registry Number.

Heterogeneous gold(I)-catalyzed hydroamination of allenamides with arylamines toward allylamino E-enamides

Jiang, Minhua,Liu, Dayi,Cai, Mingzhong

supporting information, p. 1700 - 1711 (2021/03/31)

A novel and highly efficient heterogeneous gold(I)-catalyzed hydroamination of allenamides with arylamines has been developed that proceeds effectively under mild conditions and offers a general and practical route for the synthesis of allylamino E-enamides with good to excellent yields and high stereoselectivity. The supported gold(I) catalyst can be reused at least seven times without any apparent decrease in the catalytic activity.

An intermolecular hydroamination of allenamides with arylamines catalyzed by cationic Au(I) salts

Hill, Anthony W.,Elsegood, Mark R. J.,Kimber, Marc C.

supporting information; experimental part, p. 5406 - 5409 (2010/10/02)

(Figure presented) An intermolecular hydroamination of allenamides with arylamines has been achieved under mild Au(I) catalysis conditions delivering allylamino E-enamides stereoselectively and in high yield. The reaction is made possible via a convenient method for conjugated N-acyliminium formation.
