Check Digit Verification of cas no

The CAS Registry Mumber 497838-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,8,3 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 497838-44:
(8*4)+(7*9)+(6*7)+(5*8)+(4*3)+(3*8)+(2*4)+(1*4)=225
225 % 10 = 5
So 497838-44-5 is a valid CAS Registry Number.

Antinociceptive effects of 1-acyl-4-dialkylaminopiperidine and 1-alkyl-4-dialkylaminopiperidine in mice: Structure-activity relation study of matrine-type alkaloids

, p. 1030 - 1034 (2007/10/03)

We previously reported that (+)-matrine and (+)-allomatrine have antinociceptive properties mediated mainly through the activation of κ-opioid receptors. 1-Acyl-4-dialkylaminopiperidines were synthesized as the simplest derivatives of matrine, and the structure-activity relations were examined by the acetic acid-induced abdominal contraction test. The antinociceptive potencies of 1-alkyl-4-dialkylaminopiperidines were significantly lower than those of the corresponding 1-acyl-4- dialkylaminopiperidines. These findings suggest that the amide group of (+)-matrine is an essential functional group that influences antinociceptive potency.
