Check Digit Verification of cas no

The CAS Registry Mumber 771491-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,1,4,9 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 771491-63:
(8*7)+(7*7)+(6*1)+(5*4)+(4*9)+(3*1)+(2*6)+(1*3)=185
185 % 10 = 5
So 771491-63-5 is a valid CAS Registry Number.

Unexpected formation of tetrasubstituted 2,3-dihydrofurans from the reactions of β-keto polyfluoroalkanesulfones with aldehydes

Xing, Chunhui,Zhu, Shizheng

, p. 6486 - 6488 (2004)

Catalyzed by piperidine, the reactions of β-keto polyfluoroalkanesulfones with aromatic aldehydes afforded the unexpected tetrasubstituted 2,3-dihydrofurans in good yields, probably proceeding through the normal Knoevenagel condensation products. This rea
