Check Digit Verification of cas no

The CAS Registry Mumber 19878-11-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,7 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19878-11:
(7*1)+(6*9)+(5*8)+(4*7)+(3*8)+(2*1)+(1*1)=156
156 % 10 = 6
So 19878-11-6 is a valid CAS Registry Number.

Synthesis of Acetaminophen Analogues Containing α-Amino Acids and Fatty Acids for Inhibiting Hepatotoxicity

Imai, Nobuyuki,Jung, Seunghee,Kawashima, Yuya,Noguchi, Takuya

, p. 3686 - 3696 (2019/09/30)

Acetaminophen is a popular antipyretic analgesic medicine that has weaker anti-inflammatory properties and lower incidence of side effects than nonsteroidal anti-inflammatory drugs (NSAIDs). However, acetaminophen causes hepatotoxicity due to the reactive metabolite N -acetyl- p -benzoquinone imine (NAPQI). We have obtained acetaminophen analogues in 57-99percent yields by using aniline derivatives with protected α-amino acids and fatty acids via the corresponding mixed carbonic carboxylic anhydrides in aqueous MeCN. We have also succeeded in synthesizing AM404 analogues in 76-97percent yields, which are expected to be promising candidates for reducing hepatotoxicity.
