Check Digit Verification of cas no

The CAS Registry Mumber 428868-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,8,8,6 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 428868-18:
(8*4)+(7*2)+(6*8)+(5*8)+(4*6)+(3*8)+(2*1)+(1*8)=192
192 % 10 = 2
So 428868-18-2 is a valid CAS Registry Number.

Synthesis of cyclic constrained β-oxo-substituted α-amino acids

Krikstolaityte, Sonata,Hammer, Kristin,Romming, Christian,Undheim, Kjell

, p. 571 - 580 (2002)

Ru(II)-catalyzed RCM reaction with a 5,5-diene of (2R)-2,5-dihydro-3,6-dimethoxy-2-isopropylpyrazine provided a spiroannulated cyclohexenone as substrate for conjugate additions of organocuprates. Acid hydrolysis gave β-oxo-substituted α-amino acids. Assignments of configurations are based on single crystal X-ray analyses.
