Check Digit Verification of cas no
The CAS Registry Mumber 10254-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,5 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 10254-99:
(7*1)+(6*0)+(5*2)+(4*5)+(3*4)+(2*9)+(1*9)=76
76 % 10 = 6
So 10254-99-6 is a valid CAS Registry Number.

Cycloaddition of cross-conjugated trienes to halogenated quinones
Couturier,Brassard
, p. 703 - 708 (2007/10/02)
The chemoselectivity of [4+2] cycloadditions involving electron-rich cross-conjugated trienes and halogenated quinones has been examined. The approach provides improved preparations of 6-acetyl-2,3,7-trihydroxyjuglone, solorinic and norsolorinic acids, and averythrin. It also confirms the structure proposed for haematommone and 3,8-dihydroxy-4-methoxy-2-methoxycarbonyl-1-methylanthraquinone but invalidates that of sopheranin.
