137018-23-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137018-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,1 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137018-23:
(8*1)+(7*3)+(6*7)+(5*0)+(4*1)+(3*8)+(2*2)+(1*3)=106
106 % 10 = 6
So 137018-23-6 is a valid CAS Registry Number.

Selective syntheses of unsymmetrical meso-arylporphyrins

Erna, Tadashi,Kuroda, Yasuhisa,Ogoshi, Hisanobu

, p. 4529 - 4532 (1991)

A selective synthetic route to unsymmetrical meso-arylporphyrins is described. New hybrid type of unsymmetrical porphyrin with C2v symmetry was prepared according to the new method.

Design and synthesis of a trifunctional chiral porphyrin with C2 symmetry as a chiral recognition host for amino acid esters

Mizutani, Tadashi,Ema, Tadashi,Tomita, Takashi,Kuroda, Yasuhisa,Ogoshi, Hisanobu

, p. 4240 - 4250 (2007/10/02)
