Check Digit Verification of cas no

The CAS Registry Mumber 157423-38-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,2 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 157423-38:
(8*1)+(7*5)+(6*7)+(5*4)+(4*2)+(3*3)+(2*3)+(1*8)=136
136 % 10 = 6
So 157423-38-6 is a valid CAS Registry Number.

, p. 1223 - 1226 (2007/10/02)

Degradation of AAL-toxin 1 a host-specific phytotoxin and synthesis of model aminotriol 7a-7d allowed us to determine the absolute configuration of C(1)-C(5) fragment as 2S, 4S and 5R. Unusually rigid conformation of this acyclic fragment was also discussed.
