Check Digit Verification of cas no
The CAS Registry Mumber 21912-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,1 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21912-23:
(7*2)+(6*1)+(5*9)+(4*1)+(3*2)+(2*2)+(1*3)=82
82 % 10 = 2
So 21912-23-2 is a valid CAS Registry Number.

1,3,5,7α- and 1,3,5,7β-Tetramethylbicyclo[3.3.1]nonan-3-ols 3a and 3b were prepared from the corresponding ketones 2a and 2b. 7α-Methyl isomer 3a gave selectively endo-3α-N-formylaminobicyclononane 10 in the Ritter reaction with trimethylsilyl cyanide. 7β-Methyl epimer 3b suffered water elimination resulting in bicyclo[3.3.1]non-2-ene 12 under the same reaction conditions. The endo-amide structure was confirmed by X-ray analysis. The Royal Society of Chemistry 1999.
