Check Digit Verification of cas no

The CAS Registry Mumber 404373-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,3,7 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 404373-05:
(8*4)+(7*0)+(6*4)+(5*3)+(4*7)+(3*3)+(2*0)+(1*5)=113
113 % 10 = 3
So 404373-05-3 is a valid CAS Registry Number.

An enantioselective formal synthesis of 4-demethoxydaunomycin using the catalytic asymmetric ring opening reaction of meso-epoxide with p-anisidine

Sekine, Akihiro,Ohshima, Takashi,Shibasaki, Masakatsu

, p. 75 - 82 (2002)

A catalytic asymmetric formal synthesis of 4-demethoxydaunomycin (3) was achieved using a catalytic asymmetric ring opening reaction of meso-epoxide 9 as a key step. The epoxide opening reaction was promoted by 10 mol% of Pr-(R)-BINOL-Ph3P=O co
