919769-64-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 919769-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,9,7,6 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 919769-64:
(8*9)+(7*1)+(6*9)+(5*7)+(4*6)+(3*9)+(2*6)+(1*4)=235
235 % 10 = 5
So 919769-64-5 is a valid CAS Registry Number.

Synthesis of chiral non-proteinogenic 4,5-dihydroxytetrahydropyran derived α-amino acids from d-mannitol
Brar, Anita,Vankar, Yashwant D.
, p. 9035 - 9038 (2006)
Starting from R-2,3-O-cyclohexylideneglyceraldehyde, which was obtained from d-mannitol, four tetrahydropyran derived chiral, non-proteinogenic α-amino acids have been synthesized. The key step in these syntheses is the ring closing metathesis using the f
