Check Digit Verification of cas no

The CAS Registry Mumber 1021428-00-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,4,2 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1021428-00:
(9*1)+(8*0)+(7*2)+(6*1)+(5*4)+(4*2)+(3*8)+(2*0)+(1*0)=81
81 % 10 = 1
So 1021428-00-1 is a valid CAS Registry Number.

Chiron approach to the synthesis of (2S,3R)-3-hydroxypipecolic acid and (2R,3R)-3-hydroxy-2-hydroxymethylpiperidine from D-glucose

Kalamkar, Navnath B.,Kasture, Vijay M.,Dhavale, Dilip D.

, p. 3619 - 3622 (2008/09/20)

(Chemical Equation Presented) The first chiron approach from D-glucose for the total synthesis of (2S,3R)-3-hydroxypipecolic acid (-)-1a and (2R,3R)-3-hydroxy-2-hydroxymethylpiperidine (-)-2a is reported. The synthetic pathway involves conversion of D-glucose into 3-azidopentodialdose (5) followed by the Wittig olefination and reduction to give the piperidine ring skeleton (8) with a sugar appendage that on cleavage of an anomeric carbon followed by oxidation gives (-)-1a which on reduction affords (-)-2a.
