122772-04-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122772-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,7,7 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 122772-04:
(8*1)+(7*2)+(6*2)+(5*7)+(4*7)+(3*2)+(2*0)+(1*4)=107
107 % 10 = 7
So 122772-04-7 is a valid CAS Registry Number.

Synthesis, urease and acetylcholine esterase inhibition activities of some 1,4-disubstituted thiosemicarbazides and their 2,5-disubstituted thiadiazoles

Saleem, Muhammad,Rafiq, Muhammad,Hanif, Muhammad,Rama, Nasim Hasan,Seo, Sung-Yum,Lee, Ki-Hwan

, p. 2741 - 2747 (2012/10/29)

A new series of 2,5-disubstituted-1,3,4-thiadiazoles 6a-i was synthesized by overnight stirring various 1,4-disubstituted thiosemicarbazides 5a-i in polyphosphoric acid followed by neutralization. The structures of newly synthesized compounds 5a-i and 6a-i were characterized by IR, 1H and 13C NMR, elemental analysis and mass spectrometric studies. All the synthesized compounds were evaluated for their urease and acetylcholine esterase inhibition activities. Thiosemicarbazides 5a-i are found to possess excellent potential for urease inhibition, more than the standard drug. Thiosemicarbazides 5a-i are more potent urease inhibitor than their cyclic analogues thiadiazoles 6a-i. Almost all of the compounds are excellent inhibitors of acetylcholine esterase. The inhibition of acetylcholine esterase of compounds 5a, 5c, 5d, 5g, 5i, 6e, 6f, 6g, and 6i is much more than that of standard drug.
