148903-07-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148903-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,9,0 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 148903-07:
(8*1)+(7*4)+(6*8)+(5*9)+(4*0)+(3*3)+(2*0)+(1*7)=145
145 % 10 = 5
So 148903-07-5 is a valid CAS Registry Number.

, p. 614 - 615 (1993)
The first enantiodivergent synthesis of eutypoxide B 1, a metabolite of the fungus Eutypa lata, has been accomplished in a stereo- and regio-controlled manner by using the single chiral building block 3 as a chiral equivalent of (Z)-cyclohex-2,5-dien-1,4-diol 2.
