Check Digit Verification of cas no

The CAS Registry Mumber 89404-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,0 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89404-36:
(7*8)+(6*9)+(5*4)+(4*0)+(3*4)+(2*3)+(1*6)=154
154 % 10 = 4
So 89404-36-4 is a valid CAS Registry Number.

Functionalization of (R)-3-(3-Acetoxypropyl)-2,3-dihydro-7-isopropyl-3,4-dimethylnaphthofuran-2-one and Some Related Compounds

Matsumoto, Takashi,Imai, Sachihiko,Ondo, Kenji,Kataoka, Hideo,Kato, Kyoko

, p. 2985 - 2993 (1983)

Oxidation of (R)-3-(3-acetoxypropyl)-2,3-dihydro-6-hydroxy-7-isopropyl-3,4-dimethylnaphthofuran-2-one with Fremy's radical afforded the corresponding o-quinone, which was converted into (R)-5,6,8-triacetoxy-3-(3-acetoxypropyl)-2,3-dihydro-7-isopropyl-3,4-dimethylnaphthofuran-2-one and its 5,6,9-triacetoxy isomer. (R)-3-(3-Acetoxypropyl)-2,3-dihydro-7-isopropyl-3,4-dimethylnaphthofuran-2-one was also converted into (R)-9-acetoxy- and (R)-5,8,9-triacetoxy-2,3-dihydro-7-isopropyl-3-(3-methoxypropyl)-3,4-dimethylnaphthofuran-2-one.Transformation of (R)-2,3-dihydro-6-hydroxy-3-(3-hydroxypropyl)-7-isopropyl-3,4-dimethylnaphthofuran-2-one into (R)-6-acetoxy-3-allyl-2,3-dihydro-7-isopropyl-3,4-dimethylnaphthofuran-2-one was also achieved.
