121944-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121944-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,4 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121944-70:
(8*1)+(7*2)+(6*1)+(5*9)+(4*4)+(3*4)+(2*7)+(1*0)=115
115 % 10 = 5
So 121944-70-5 is a valid CAS Registry Number.

BICYCLO NONANE APPROACH TO PINGUISANE TERPENOIDS.TOTAL SYNTHESIS OF (+/-) PINGUISONE
Gambacorta, A.,Botta, M.,Turchetta, S.
, p. 4837 - 4846 (2007/10/02)
The total synthesis of (+/-) pinguisone 1, the sterically crowded unusual fused-ring sesquiterpene, was accomplished by synthetic elaboration of the 3β,3aβ,7,7aβ-tetramethylbicyclo non-6-en-1-one 2a prepared by acid catalyzed rearrangement o
