97253-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97253-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97253-40:
(7*9)+(6*7)+(5*2)+(4*5)+(3*3)+(2*4)+(1*0)=152
152 % 10 = 2
So 97253-40-2 is a valid CAS Registry Number.

Synthesis of the antileukemic agent (±)-steganone using a stereoconvergent biaryl coupling reaction
Magnus,Schultz,Gallagher
, p. 4984 - 4988 (2007/10/02)
The total synthesis of (±)-steganone (4) has been achieved in a stereoselective manner from piperonal. The cinnamate derivative 15 was oxidized by using Tl(OCOCF3)3 in TFA to give the biaryl 26 (81%). Reduction of 26 with LiAlH4
