Calculate Digit Verification of CAS Registry Number 13558-73:
(7*1)+(6*3)+(5*5)+(4*5)+(3*8)+(2*7)+(1*3)=111
111 % 10 = 1
So 13558-73-1 is a valid CAS Registry Number.

A concise approach to n-substituted rhodanines through a base-assisted one-pot coupling and cyclization process

Huo, Zhipeng,Liang, Yongxi,Sun, Xun,Tang, Mei-Lin,Zhang, Chenchen

, (2020)

An efficient approach to obtain functionalized rhodanines was developed through a base-assisted one-pot coupling and continuous cyclization of a primary amine, carbon disulfide, and methyl (2-chloroacetyl)carbamate. This conversion tolerates a broad range of functional groups and can be used to scale the preparation of N-substituted rhodanines in excellent yields.
