Check Digit Verification of cas no

The CAS Registry Mumber 30021-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,0,2 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30021-94:
(7*3)+(6*0)+(5*0)+(4*2)+(3*1)+(2*9)+(1*4)=54
54 % 10 = 4
So 30021-94-4 is a valid CAS Registry Number.

A straightforward access to neohesperidose from naringin by acetolysis. Comparative behaviour of some flavonoid neohesperidosides and rutinosides under acetolysis

Lewin, Guy

, p. 1492 - 1496 (2014/02/14)

A straightforward semisynthesis of neohesperidose was performed in three-steps with 43% overall yield starting from naringin, the main flavonoid of grapefruit. In addition, the behaviour of two pairs of flavonoid 7-O-rhamnoglucosides (neohesperidosides naringin and rhoifolin; rutinosides hesperidin and diosmin) under same acetolysis conditions was compared. Results demonstrated the crucial influence of the oxidation state of the aglycone (flavanone or flavone), and of the nature of the disaccharidic moiety on the course of the reaction.
