17934-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17934-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,3 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17934-14:
(7*1)+(6*7)+(5*9)+(4*3)+(3*4)+(2*1)+(1*4)=124
124 % 10 = 4
So 17934-14-4 is a valid CAS Registry Number.

A highly enantioselective synthesis of (R)- and (S)-5,7-odimethyleucomol
Davis, Franklin A.,Chen, Bang-Chi
, p. 6823 - 6826 (1990)
Both (R)- and (S)-5,7-O-dimethyleucomol 1b (R = Me) were synthesized in 57% overall yield in>96% enantiomeric excess. The key step involves the enantioselective α hydroxylation of the lithium enolate of 8 by readily available (+)- and (-)-[(8,8-dimethoxyc
