189265-59-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189265-59-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,6 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 189265-59:
(8*1)+(7*8)+(6*9)+(5*2)+(4*6)+(3*5)+(2*5)+(1*9)=186
186 % 10 = 6
So 189265-59-6 is a valid CAS Registry Number.

Radical cyclisation with high diastereofacial selectivity: Asymmetric synthesis of (+)-12b-epidevinylantirhine
Ihara, Masataka,Katsumata, Akira,Fukumoto, Keiichiro
, p. 991 - 992 (2007/10/03)
Radical cyclisation of the chiral α,β-unsaturated ester 1, carried out in the presence of MAD, gives six-membered cyclic acetal 2 diastereoselectively, which is transformed into (+)-12b-epidevinylantirhine 7.
