Check Digit Verification of cas no

The CAS Registry Mumber 55-16-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55-16:
(4*5)+(3*5)+(2*1)+(1*6)=43
43 % 10 = 3
So 55-16-3 is a valid CAS Registry Number.

Stereochemistry of the 1,2-migration of the carboxyl group that occurs during the biosynthesis of tropic acid from phenylalanine

Leete, Edward

, p. 226 - 228 (2007/10/02)

(2S,3R)- and (2S,3S)-phenylalanine were fed in separate experiments to Datura innoxia plants.The distribution of isotopes in the resultant labeled hyoscyamine and scopolamine indicates that the biosynthesis of the acid moiety of these ester alkaloids, namely (S)-tropic acid, involves the migration of the carboxyl group of phenylalanine to its prochiral C-3 position with retention of configuration.
