Check Digit Verification of cas no

The CAS Registry Mumber 1412409-44-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,2,4,0 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1412409-44:
(9*1)+(8*4)+(7*1)+(6*2)+(5*4)+(4*0)+(3*9)+(2*4)+(1*4)=119
119 % 10 = 9
So 1412409-44-9 is a valid CAS Registry Number.

Synthesis of 5, 6-dichloroindan-1-acids and their tetrazolyl derivatives as analgesic and anti-inflammatory agents

Pal, Rajib Kumar,Yasmin, Hasina,Nahar, Lutfun,Datta, Bidyut Kanti,Kundu, Joydeb Kumar,Bachar, Sitesh Chandra,Chowdhury, Abul Kalam Azad,Sarker, Satyajit Dey

, p. 874 - 882,9 (2020/08/31)

Indan derivatives, namely, 5-(5′,6′-dichloroindan-1′-yl)- tetrazole (12a) and 5-(5′,6′-dichloroindan-1′-yl)- methyltetrazole (12b), were synthesized conveniently from 5,6-dichloroindan-1- carboxylic acid (9a) and 5,6- dichloroindan-1-acetic acid (9b), respectively, as potential analgesic and anti-inflammatory agents. The analgesic and anti-inflammatory properties of 9a, 9b, 12a and 12b were evaluated by the acetic acid induced writhing in Swiss albino mice and the carrageenan-induced rat paw edema models, respectively. Compounds 9a and 12a exhibited significant analgesic activity with the doses of 50 and 100 mg/kg body weight, comparable to that of the positive controls, phenylbutazone, indomethacin and aminopyrine. The anti-inflammatory potencies of 9a and 12a were also comparable to that of the positive control, phenylbutazone. Compounds 9b and 12b showed analgesic and anti-inflammatory activities, but were weaker than that of compounds 9a and 12a.
