Check Digit Verification of cas no

The CAS Registry Mumber 627099-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,7,0,9 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 627099-18:
(8*6)+(7*2)+(6*7)+(5*0)+(4*9)+(3*9)+(2*1)+(1*8)=177
177 % 10 = 7
So 627099-18-7 is a valid CAS Registry Number.

Synthesis of 3-Aminochroman Derivatives by Radical Cyclization

Pave, Gregoire,Usse-Versluys, Stephanie,Viaud-Massuard, Marie-Claude,Guillaumet, Gerald

, p. 4253 - 4256 (2007/10/03)

(Equation presented) Enantiomerically pure 5-acetyl-3-amino-3,4-dihydro-2H- 1-benzopyran and methyl 3-amino-3,4-dihydro-2H-1-benzopyran-5-carboxylate were successfully synthesized starting from D- or L-serine. The formation of the benzopyran ring involved a radical cyclization step. The enantiomeric purities of the final aminochroman derivatives were determined by capillary electrophoresis using β-cyclodextrins as a chiral selector.
