387337-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 387337-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,7,3,3 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 387337-83:
(8*3)+(7*8)+(6*7)+(5*3)+(4*3)+(3*7)+(2*8)+(1*3)=189
189 % 10 = 9
So 387337-83-9 is a valid CAS Registry Number.

Stereoelectronic effects in the DIBAL reduction of aryl-1,2-ethanediol benzylidene acetals
Gauthier Jr., Donald R,Szumigala Jr., Ronald H,Armstrong III, Joseph D,Volante
, p. 7011 - 7014 (2007/10/03)
Reduction of benzylidene acetal 8 with DIBAL-H selectively gave 4 in 89% yield. 1-Aryl-1,2-diol benzylidene acetals display unusual regioselectivity with electron withdrawing groups on the aryl group.
