Check Digit Verification of cas no

The CAS Registry Mumber 83300-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,0 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83300-69:
(7*8)+(6*3)+(5*3)+(4*0)+(3*0)+(2*6)+(1*9)=110
110 % 10 = 0
So 83300-69-0 is a valid CAS Registry Number.

Resolution of homoallylic alcohols containing dithioketene acetal functionalities. Synthesis of optically active γ-lactones by a combination of chemical and enzymatic methods

Pai,Fang,Wu

, p. 6018 - 6025 (2007/10/02)

Racemic homoallylic alcohols 1-3 containing dithioketeneacetal functionalities were prepared by addition of aldehydes to the allylic anions of ketene dithioacetals or 2-alkenyl-1,3-dithiane in a regio- and stereoselective manner. Lipase-catalyzed hydrolyses of the corresponding acetates 7-9 afforded optically active alcohols 1-3, which were treated with mercuric chloride to give γ-lactones such as natural hop lactone, whiskey lactone, and cognac lactone.
