1422545-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422545-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,5,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1422545-91:
(9*1)+(8*4)+(7*2)+(6*2)+(5*5)+(4*4)+(3*5)+(2*9)+(1*1)=142
142 % 10 = 2
So 1422545-91-2 is a valid CAS Registry Number.

(-)-Astrogorgiadiol: A shorter route to A-ring synthon
Médard, Guillaume
, p. 2348 - 2351 (2013/03/29)
A new route to the key A-ring/C-ring precursor synthon of (-)-astrogorgiadiol is described, for the strategy based on Robinson annulation. This synthon is also key for the synthesis of other related calicoferols and astrogorgols. The route takes full adva
