Check Digit Verification of cas no

The CAS Registry Mumber 78805-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,0 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78805-21:
(7*7)+(6*8)+(5*8)+(4*0)+(3*5)+(2*2)+(1*1)=157
157 % 10 = 7
So 78805-21-7 is a valid CAS Registry Number.

Stereocontrolled Addition Reaction of Organometallics to Chiral α-Keto Amides

Fujisawa, Tamotsu,Ukaji, Yutaka,Funabora, Makoto,Yamashita, Mikio,Sato, Toshio

, p. 1894 - 1897 (2007/10/02)

Complementary stereoselection in the addition reaction of several organometallics to chiral benzoylformamide, prepared from benzoylformic acid and (S)-2-(methoxymethyl)pyrrolidine, could be achieved using magnesium- and titanium-based reagents to give different diastereomers of atrolactamide.On the other hand, the reaction of phenyl metallics to the corresponding pyruvamide afforded (S)-atrolactamide.
