Check Digit Verification of cas no

The CAS Registry Mumber 775348-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,5,3,4 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 775348-40:
(8*7)+(7*7)+(6*5)+(5*3)+(4*4)+(3*8)+(2*4)+(1*0)=198
198 % 10 = 8
So 775348-40-8 is a valid CAS Registry Number.

Facile synthesis of non-nucleoside compounds starting from a-chlorocarbenium ions and isocyanates as potential hiv-1 reverse transcriptase inhibitors

Hamed, Atef A.,Zeid, Ibrahim F.,Manaa, Alaa A.

experimental part, p. 555 - 564 (2010/03/03)

Chloro(phenyl)carbenium hexachloroantimonate salts react with isocyanates to afford either isoindolium (1) or benzoxazinium salts (2). Addition of one equivalent of alcohol to 2 led, after hydrolysis with aq. NaOH, to the formation of benzoxazin-2-ones 3. Treatment with a large excess of alcohol transformed the salts 1 and 2 to the corresponding isoindol-1-ones 11 and the isocyanates 5, respectively. Reaction of 5 with primary amines furnished the urea derivatives 6 in good yield. The biological activity of 6a - o against HIV-1 was determined.
