93862-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93862-55-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,6 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 93862-55:
(7*9)+(6*3)+(5*8)+(4*6)+(3*2)+(2*5)+(1*5)=166
166 % 10 = 6
So 93862-55-6 is a valid CAS Registry Number.

Enantioselective Ring Construction: Synthesis of (+)-α-Cuparenone
Taber, Douglass F.,Petty, Eric H.,Raman, Krishna
, p. 196 - 199 (2007/10/02)
Rhodium-catalyzed intramolecular C-H insertion (8->9) is shown to proceed with retention of absolute configuration.The product β-keto ester 9 is readily carried on to (+)-α-cuparenone (10).This represents a general strategy for the enantioselective formu
