Check Digit Verification of cas no

The CAS Registry Mumber 1183031-46-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,3,0,3 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1183031-46:
(9*1)+(8*1)+(7*8)+(6*3)+(5*0)+(4*3)+(3*1)+(2*4)+(1*6)=120
120 % 10 = 0
So 1183031-46-0 is a valid CAS Registry Number.

Discovery of pyrazinone based compounds that potently inhibit the drug-resistant enzyme variant R155K of the hepatitis C virus NS3 protease

Belfrage, Anna Karin,Abdurakhmanov, Eldar,?kerblom, Eva,Brandt, Peter,Oshalim, Anna,Gising, Johan,Skogh, Anna,Neyts, Johan,Danielson, U. Helena,Sandstr?m, Anja

, p. 2603 - 2620 (2016/06/08)

Herein, we present the design and synthesis of 2(1H)-pyrazinone based HCV NS3 protease inhibitors with variations in the C-terminus. Biochemical evaluation was performed using genotype 1a, both the wild-type and the drug resistant enzyme variant, R155K. S

A phosgene and peroxide-free one-pot tandem synthesis of isatoic anhydrides involving anthranilic acid, boc anhydride and 2-chloro-N-methyl pyridinium iodide

Verma, Chhaya,Sharma, Somesh,Pathak, Arunendra

supporting information, p. 6897 - 6899 (2019/04/10)

A phosgene and peroxide-free approach for the synthesis of isatoic anhydrides has been described. The synthesis involves the carbamate formation with boc anhydride followed by in situ cyclization to afford the isatoic anhydride. The importance of this synthetic strategy is in the ease of operation, scalability and preparation from readily available raw materials.
