Check Digit Verification of cas no

The CAS Registry Mumber 212892-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,8,9 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 212892-03:
(8*2)+(7*1)+(6*2)+(5*8)+(4*9)+(3*2)+(2*0)+(1*3)=120
120 % 10 = 0
So 212892-03-0 is a valid CAS Registry Number.

Synthetic approaches to 2-(4-hydroxy-7-chromanyl)benzoic acids as antagonists of leukotriene B4

Chambers,Koch,Biggers,Ramchandani

, p. 1787 - 1790 (1998)

Structural modification of 1 led to a series of 2-(4-hydroxy-7- chromanyl)benzoic acid LTB4 antagonists exemplified by 2 and 3. The use of an organostannane biaryl coupling, a non stereoselective reduction and a chromatographic resolution limited the utility of this synthetic route. To address these issues, a new synthetic route was developed utilizing a palladium catalyzed coupling of aryl oxazolines in tandem with a stereospecific enone reduction as key synthetic steps. Resolution was achieved by fractional crystallization of a (S)-(-)-α-methylbenzylamine salt.
