497236-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 497236-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,2,3 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 497236-39:
(8*4)+(7*9)+(6*7)+(5*2)+(4*3)+(3*6)+(2*3)+(1*9)=192
192 % 10 = 2
So 497236-39-2 is a valid CAS Registry Number.

Total synthesis of lavendamycin by a [2+2+2] cycloaddition
Nissen, Felix,Detert, Heiner
, p. 2845 - 2853 (2011/06/26)
The total synthesis of the bacterial-derived, pentacyclic, antitumor antibiotic lavendamycin has been achieved through a highly convergent strategy. The key step of this synthesis is a ruthenium-catalyzed [2+2+2] cycloaddition of an electron-deficient nit
