63385-20-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63385-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,3,8 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 63385-20:
(7*6)+(6*3)+(5*3)+(4*8)+(3*5)+(2*2)+(1*0)=126
126 % 10 = 6
So 63385-20-6 is a valid CAS Registry Number.

Metal-free three-component synthesis of thioamides from β-nitrostyrenes, amines and elemental sulfur

Peng, Ling,Ma, Li,Ran, Ying,Chen, Yunfeng,Zeng, Zhigang

, (2021)

A metal-free C[dbnd]C bond cleavage reaction of β-nitrostyrenes in the presence of elemental sulfur and secondary amines/amides is described. Elemental sulfur serves as both a raw material and an oxidant for C[dbnd]C bond cleavage, and secondary amines or amides are both feasible nitrogen sources. Besides mild reaction condition and simple work-up procedure, the method provided thioamides with good to excellent yields.

K2S2O8-promoted aryl thioamides synthesis from aryl aldehydes using thiourea as the sulfur source

Bian, Yongjun,Qu, Xingyu,Chen, Yongqiang,Li, Jun,Liu, Leng

, (2018/09/10)

Thiourea as a sulfur atom transfer reagent was applied for the synthesis of aryl thioamides through a three-component coupling reaction with aryl aldehydes and N,N-dimethylformamide (DMF) or N,N-dimethylacetamide (DMAC). The reaction could tolerate various functional groups and gave moderate to good yields of desired products under the transition-metal-free condition.
