72702-27-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72702-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,0 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72702-27:
(7*7)+(6*2)+(5*7)+(4*0)+(3*2)+(2*2)+(1*7)=113
113 % 10 = 3
So 72702-27-3 is a valid CAS Registry Number.

Synthesis of Erythrinin-A and Related Isoflavones
Jain, A. C.,Gupta, S.,Gupta, A.,Bambah, P.
, p. 609 - 613 (2007/10/02)
Erythrinin-A (1) is best synthesized by the condensation of 6-acetyl-7-hydroxy-2,2-dimethylchroman (15) with p-methoxymethoxybenzaldehyde in the presence of alkali followed by oxidative rearrangement of the resulting chalcone (16) with Tl(NO3)3 in MeOH, d
