88220-92-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88220-92-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,2 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 88220-92:
(7*8)+(6*8)+(5*2)+(4*2)+(3*0)+(2*9)+(1*2)=142
142 % 10 = 2
So 88220-92-2 is a valid CAS Registry Number.

New 4,5 (3H)dihydro-4-acetyl-2-furanones derivatives: Chemical and pharmacological study
Couquelet,Taoufik,Couquelet,et al.
, p. 301 - 305 (2007/10/02)
5-substituted 4,5 (3H)-dihydro 4-acetyl 2-furanones were synthetized by reaction of aromatic heteroaromatic or cyclanic aldehydes with α-angelicalactone in presence of boron trifluoride. We showed from NMR spectroscopic data that the reaction course was s
