257878-00-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 257878-00-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,8,7 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 257878-00:
(8*2)+(7*5)+(6*7)+(5*8)+(4*7)+(3*8)+(2*0)+(1*0)=185
185 % 10 = 5
So 257878-00-5 is a valid CAS Registry Number.

Enantioselective synthesis of cyclopropane aminoalcohols containing quaternary stereogenic centers
Rife, Joan,Ortuno, Rosa M.
, p. 4245 - 4260 (1999)
Some title compounds have been synthesized in enantiomerically pure form starting from D- or L-glyceraldehyde as chiral precursors. A new synthesis of (+)-(Z)-methanohomoserine, one of the key intermediates employed, is also described. The target molecule
