Check Digit Verification of cas no

The CAS Registry Mumber 134614-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,1 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134614-22:
(8*1)+(7*3)+(6*4)+(5*6)+(4*1)+(3*4)+(2*2)+(1*2)=105
105 % 10 = 5
So 134614-22-5 is a valid CAS Registry Number.

POLYSUBSTITUTED 4-PIPERIDONES AND 4-PIPERIDOLS: SYNTHESIS AND SPATIAL CONFIGURATION

Belostotskii, A. M.,Shapiro, A. B.

, p. 421 - 429 (2007/10/02)

Triacetonamine was used to synthesize a series of highly substituted 4-piperidones and 4-piperidols.The spatial configuration of these compounds was determined.The anionoid addition to the carbonyl group of these piperidones proceeds through highly stereoselective equatorial attack.The position of the chair-chair-twist conformational equilibrium was determined for the polysubstituted 4-piperidols.
