Check Digit Verification of cas no

The CAS Registry Mumber 190850-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,8,5 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 190850-56:
(8*1)+(7*9)+(6*0)+(5*8)+(4*5)+(3*0)+(2*5)+(1*6)=147
147 % 10 = 7
So 190850-56-7 is a valid CAS Registry Number.

Stereocontrolled Mukaiyama-type Aldol Reaction of Siloxypyrroles Derived from (S)-Glutamic Acid

Uno, Hidemitsu,Baldwin, Jack E.,Churcher, Ian,Russell, Andrew T.

, p. 390 - 392 (1997)

The stereochemistry of the Lewis acid catalysed Mukaiyama-type aldol reaction of 5-tert-butyldimethylsiloxy-3-phenyl-1H-pyrrolo[1,2-e]oxazoles with isobutyraldehyde was dependant on the nature of the Lewis acid, SnCl4 and BF3·OEt2 giving predominantly isomeric products.
