Check Digit Verification of cas no
The CAS Registry Mumber 31004-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,0 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31004-27:
(7*3)+(6*1)+(5*0)+(4*0)+(3*4)+(2*2)+(1*7)=50
50 % 10 = 0
So 31004-27-0 is a valid CAS Registry Number.

The deprotonation of 3-substituted-furan-2(5H)-ones 1, obtained via the hydrolysis of 3-substituted-2,5-dihydro-2,5-dimethoxyfurans, affords in the reaction with both aromatic and aliphatic aldehydes regioselectively the unsaturated 3-substituted 5-(1′-hydroxy)-γ-butyrolactones, such as 4, 5, 6, 7, 8, 9 and 10. The use of Lewis acids allows modulation of the diastereoisomeric ratios. The subsequent reduction, carried out with nickel boride, gives rise to the formation of the corresponding saturated 5-(1′-hydroxy)-γ-butyrolactones, such as 11, 12 and 13.
