Check Digit Verification of cas no
The CAS Registry Mumber 157430-14-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,3 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157430-14:
(8*1)+(7*5)+(6*7)+(5*4)+(4*3)+(3*0)+(2*1)+(1*4)=123
123 % 10 = 3
So 157430-14-3 is a valid CAS Registry Number.

Mitsunobu reactions of glycals with phenoxide nucleophiles are S(N)2'-selective
Sobti,Sulikowski
, p. 3661 - 3664 (1994)
The C3-hydroxyl group of L-rhamnal (4) and D-glucal 7 underwent S(N)2'-selective Mitsunobu displacements with substituted phenoxide nucleophiles. These reactions provide access to the corresponding α-arylglycoside.
