Check Digit Verification of cas no

The CAS Registry Mumber 383421-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,3,4,2 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 383421-27:
(8*3)+(7*8)+(6*3)+(5*4)+(4*2)+(3*1)+(2*2)+(1*7)=140
140 % 10 = 0
So 383421-27-0 is a valid CAS Registry Number.

A porphyrin tetramer for a positive homotropic allosteric recognition system: Efficient binding information transduction through butadiynyl axis rotation

Kubo, Yohei,Ikeda, Masato,Sugasaki, Atsushi,Takeuchi, Masayuki,Shinkai, Seiji

, p. 7435 - 7438 (2001)

A porphyrin tetramer 1 was newly designed and synthesized to construct a novel allosteric guest-binding system. Compound 1 has a butadiynyl rotational axis, which is expected to act as a guest-binding information transducer. In chloroform, 1 can bind bidentate amines, such as 1,3-di(4-piperidyl)propane (DPP), in an allosteric manner to produce a 1:2 1/diamine complex with a Hill coefficient of 1.9.
