Check Digit Verification of cas no

The CAS Registry Mumber 646066-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,6,0,6 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 646066-05:
(8*6)+(7*4)+(6*6)+(5*0)+(4*6)+(3*6)+(2*0)+(1*5)=159
159 % 10 = 9
So 646066-05-9 is a valid CAS Registry Number.

MIRC reactions of 2-bromo-5-(l-menthyloxy)furan-2(5H)-one with stabilized anions. Preparation of homochiral bicyclic γ-butyrolactones

Maestro, M. Carmen,Barquilla, M. Cruz,Martin, M. Rosario

, p. 3593 - 3599 (1999)

Homochiral (5R)-4-bromo-5-(l-menthyloxy)furan-2(5H)-one with stabilized carbanions (from nitroalkanes, malononitrile and ethyl acetoacetate) afforded enantiopure bicyclic compounds in good yield (70-90%). 3- Oxabicyclic[3.1.0]hexan-2-one derivatives were obtained with nitromethane and malonic acid derivatives. However, dihydrofuro[3,4-d]isoxazol-6-one and dihydrofuro[3,4-b]furan-6(4H)-one derivatives were obtained from nitroethane and ethyl acetoacetate, respectively.
