133765-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133765-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,6 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133765-69:
(8*1)+(7*3)+(6*3)+(5*7)+(4*6)+(3*5)+(2*6)+(1*9)=142
142 % 10 = 2
So 133765-69-2 is a valid CAS Registry Number.

Enantioselective Synthesis of the Lactone Moiety of the Mevinic Acids using D-Xylose as a Chiral Precursor
Ballini, Roberto,Marcantoni, Enrico,Petrini, Marino
, p. 490 - 491 (2007/10/02)
Homologation of the lactone 14 easily obtained from D-xylose afforded the pyranone 15, a key chiral synthon for the lactone portion of mevinic acids.
