The CAS Registry Mumber 13031-06-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,3 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13031-06:
(7*1)+(6*3)+(5*0)+(4*3)+(3*1)+(2*0)+(1*6)=46
46 % 10 = 6
So 13031-06-6 is a valid CAS Registry Number.

Reversal of Regioselectivity in the Reduction of gem-Disubstituted Cyclic Carboxylic Acid Anhydrides

Morand, Peter,Salvator, Judith,Kayser, Margaret M.

, p. 458 - 459 (1982)

The regioselective partial reduction of gem-disubstituted cyclic carboxylic acid anhydrides to the corresponding γ-lactones with LiAlH4 or NaBH4 is almost completely reversed when potassium tri-s-butylborohydride is used as the reducing agent.
