The CAS Registry Mumber 1417803-54-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,8,0 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1417803-54:
(9*1)+(8*4)+(7*1)+(6*7)+(5*8)+(4*0)+(3*3)+(2*5)+(1*4)=153
153 % 10 = 3
So 1417803-54-3 is a valid CAS Registry Number.

Asymmetric total syntheses of xanthatin and 11,13-dihydroxanthatin using a stereocontrolled conjugate allylation to γ-butenolide

Matsumoto, Kenji,Koyachi, Kuniyoshi,Shindo, Mitsuru

, p. 1043 - 1049 (2013/02/23)

The stereocontrolled conjugate allylation to an optically pure γ-butenolide provided direct and reliable access to a trans-fused series of xanthanolide sesquiterpenoids and allowed for the enantioselective total syntheses of xanthatin and 11,13-dihydroxanthatin to be efficiently achieved.
