Check Digit Verification of cas no

The CAS Registry Mumber 126188-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,1,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126188-20:
(8*1)+(7*2)+(6*6)+(5*1)+(4*8)+(3*8)+(2*2)+(1*0)=123
123 % 10 = 3
So 126188-20-3 is a valid CAS Registry Number.

EFFICIENT TOTAL SYNTHESES OF POLYGODIAL AND DRIMENIN.

Jallali-Naini, M.,Boussac, G.,Lemaitre, P.,Larcheveque, M.,Guillerm, D.,Lallemand, J-Y

, p. 2995 - 2998 (1981)

A short and stereoselective total synthesis of (+/-) polygodial and drimenin is presented.The efficiency of the synthesis is due to the easy access to intermediate diol 4 and its successful direct oxidation into polygodial.

Synthesis of all possible stereoisomers of polygodial

Guillerm, D.,Delarue, M.,Jalali-Naini, M.,Lemaitre, P.,Lallemand, J.-Y.

, p. 1043 - 1046 (2007/10/02)

The three possible isomers of polygodial, epimers at C-9, cis and trans fused, are described.Controlled kinetic and thermodynamic epimerizations allow preparation of all stereoisomers from the same key intermediate.
