Check Digit Verification of cas no

The CAS Registry Mumber 1046799-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,6,7,9 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1046799-53:
(9*1)+(8*0)+(7*4)+(6*6)+(5*7)+(4*9)+(3*9)+(2*5)+(1*3)=184
184 % 10 = 4
So 1046799-53-4 is a valid CAS Registry Number.

Total synthesis of cleomiscosin C via a regioselective cycloaddition reaction of o-quinone

Kuboki, Atsuhito,Maeda, Chie,Arishige, Tetsuya,Kuyama, Kohei,Hamabata, Mami,Ohira, Susumu

, p. 4516 - 4518 (2008/09/21)

We have achieved total synthesis of cleomiscosin C (aquillochin) through regioselective cycloaddition of o-quinone and protected sinapyl alcohol as a key step. During preparation of o-quinone from phenol by IBX oxidation, silyl substituents adjacent to the phenolic hydroxyl group afforded effective inhibition of an undesired oxidative elimination.
