66364-50-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66364-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,6 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66364-50:
(7*6)+(6*6)+(5*3)+(4*6)+(3*4)+(2*5)+(1*0)=139
139 % 10 = 9
So 66364-50-9 is a valid CAS Registry Number.

Synthesis and structure-activity relationships of a new class of 1-oxacephem-based human chymase inhibitors

Aoyama, Yasunori,Uenaka, Masaaki,Konoike, Toshiro,Iso, Yasuyoshi,Nishitani, Yasuhiro,Kanda, Akiko,Naya, Noriyuki,Nakajima, Masatoshi

, p. 2397 - 2401 (2007/10/03)

1-Oxacephem derivatives were synthesized and evaluated as a novel series of chymase inhibitors. Structure-activity relationship studies of 1-oxacephems led to compound 34, which exhibited 6 nM inhibition of human chymase and high selectivity for human chymase compared to other serine enzymes.
