Check Digit Verification of cas no
The CAS Registry Mumber 161562-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,5,6 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161562-24:
(8*1)+(7*6)+(6*1)+(5*5)+(4*6)+(3*2)+(2*2)+(1*4)=119
119 % 10 = 9
So 161562-24-9 is a valid CAS Registry Number.

A Novel Synthetic Route to Enantiomers of ε-Hydroxynorleucine and ε-Chloronorleucine from L- and D,L-Lysine
Belyaev, Alexander A.
, p. 439 - 440 (2007/10/02)
Thermal rearrangement of (S)- or (R)-hexahydro-1-nitroso-3-phthalimido-2H-azepin-2-one to te corresponding lactone followed by nucleophilic ring opening of the latter gives ε-chloro- or ε-hydroxynorleucine.
