Check Digit Verification of cas no
The CAS Registry Mumber 154520-16-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,5,2 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 154520-16:
(8*1)+(7*5)+(6*4)+(5*5)+(4*2)+(3*0)+(2*1)+(1*6)=108
108 % 10 = 8
So 154520-16-8 is a valid CAS Registry Number.

Chiral 2-cyano esters as synthetic intermediates in the synthesis of R and S-α-methylvaline
Cativiela,Diez-De-Villegas,Galvez,Lapena
, p. 5921 - 5928 (1995)
A divergent stereoselective synthesis of R and S α-methylvaline from (2RS) (1S,2R,4R)-10-dicyclohexylsulfamoylisobornyl 2-cyano-3-methylbutanoate has been developed.
