Check Digit Verification of cas no

The CAS Registry Mumber 557090-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,0,9 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 557090-30:
(8*5)+(7*5)+(6*7)+(5*0)+(4*9)+(3*0)+(2*3)+(1*0)=159
159 % 10 = 9
So 557090-30-9 is a valid CAS Registry Number.

Synthesis of ketosyl spiro-isoxazolidine by 1,3-dipolar cycloaddition of 1-methylenesugars with nitrones - A new access to C-glycosyl amino acids

Li, Xiaoliu,Takahashi, Hideyo,Ohtake, Hiro,Ikegami, Shiro

, p. 547 - 571 (2007/10/03)

The 1,3-dipolar cycloaddition reactions of 1-methylenesugars (1a-c) with nitrones (2 and 5) were carried out diastereoselectively under the catalysis of BF3·Et2O at low temperature and afforded the α-stereoselective spiro ketosyl iso
