Check Digit Verification of cas no

The CAS Registry Mumber 1637595-59-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,7,5,9 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1637595-59:
(9*1)+(8*6)+(7*3)+(6*7)+(5*5)+(4*9)+(3*5)+(2*5)+(1*9)=215
215 % 10 = 5
So 1637595-59-5 is a valid CAS Registry Number.

Gold-Catalyzed Cyclisation by 1,4-Dioxidation

Claus, Vanessa,Molinari, Lise,Büllmann, Simon,Thusek, Jean,Rudolph, Matthias,Rominger, Frank,Hashmi, A. Stephen K.

, p. 9385 - 9389 (2019)

Amide-substituted diynes were cyclized in the presence of a cationic gold catalyst and an external nucleophile leading to 1-indenones and 1-iminoindenones. The electron-donating features of the nitrogen atom enable the formation of a reactive ketene iminium ion, which can be trapped by either diphenyl sulfoxide or anthranil as nucleophiles in a subsequent oxidation step, providing substituted inden-1-on-3-carboxamides.
