Check Digit Verification of cas no

The CAS Registry Mumber 55094-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,0,9 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55094-52:
(7*5)+(6*5)+(5*0)+(4*9)+(3*4)+(2*5)+(1*2)=125
125 % 10 = 5
So 55094-52-5 is a valid CAS Registry Number.

Weinreb Amide Approach to the Practical Synthesis of a Key Remdesivir Intermediate

Xie, Yuanchao,Hu, Tianwen,Zhang, Yan,Wei, Daibao,Zheng, Wei,Zhu, Fuqiang,Tian, Guanghui,Aisa, Haji A.,Shen, Jingshan

, p. 5065 - 5072 (2021/04/12)

Currently, remdesivir is the first and only FDA-approved antiviral drug for COVID-19 treatment. Adequate supplies of remdesivir are highly warranted to cope with this global public health crisis. Herein, we report a Weinreb amide approach for preparing the key intermediate of remdesivir in the glycosylation step where overaddition side reactions are eliminated. Starting from 2,3,5-tri-O-benzyl-d-ribonolactone, the preferred route consisting of three sequential steps (Weinreb amidation, O-TMS protection, and Grignard addition) enables a high-yield (65%) synthesis of this intermediate at a kilogram scale. In particular, the undesirable PhMgCl used in previous methods was successfully replaced by MeMgBr. This approach proved to be suitable for the scalable production of the key remdesivir intermediate.
