733010-81-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 733010-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,3,0,1 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 733010-81:
(8*7)+(7*3)+(6*3)+(5*0)+(4*1)+(3*0)+(2*8)+(1*1)=116
116 % 10 = 6
So 733010-81-6 is a valid CAS Registry Number.

Toward the total synthesis of methyl isosartortuoate: Construction of the backbone of the diene unit
Liu, Peng,Xu, Xingxiang
, p. 5163 - 5166 (2007/10/03)
The backbone of diene precursor in the proposed biogenesis of methyl isosartortuoate through a Diels-Alder reaction has been constructed via dehydration to establish the conjugated system; and double cyclization by using Horner-Wittig-Emmons reaction and
