Check Digit Verification of cas no

The CAS Registry Mumber 90872-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,7 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90872-92:
(7*9)+(6*0)+(5*8)+(4*7)+(3*2)+(2*9)+(1*2)=157
157 % 10 = 7
So 90872-92-7 is a valid CAS Registry Number.

An Efficient Catalytic Amidation of Esters Promoted by N-Heterocyclic Carbenes

Chen, Ling-Yan,Wu, Mei-Fang

, p. 1595 - 1602 (2019)

An efficient NHC-catalyzed amidation between esters and amines or hydrazines is described. This strategy was tolerant for a wide scope of substrates, affording a series of amides (or hydrazides) in good to excellent yields (60-96%) under simple conditions. The approach was also used to synthesize the pharmaceutically relevant antidepressant moclobemide in 85% yield.
