Check Digit Verification of cas no
The CAS Registry Mumber 116558-22-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,5 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 116558-22:
(8*1)+(7*1)+(6*6)+(5*5)+(4*5)+(3*8)+(2*2)+(1*2)=126
126 % 10 = 6
So 116558-22-6 is a valid CAS Registry Number.

REACTION OF BUTYLLITHIUM WITH BENZYLIDENE ACETALS OF ALDOPYRANOSIDES AND 1,5-ANHYDROALDITOLS
Horton, Derek,Weckerle, Wolfgang
, p. 305 - 312 (2007/10/02)
Under suitable conditions, butyllithium selectively cleaves 5-membered benzylidene acetals (1,3-dioxolane ring) leaving the 6-membered analogs (1,3-dioxane ring) intact in aldopyranoside and 1,5-anhydroalditol derivatives.The usual course of the reaction
