72471-47-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72471-47-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,7 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72471-47:
(7*7)+(6*2)+(5*4)+(4*7)+(3*1)+(2*4)+(1*7)=127
127 % 10 = 7
So 72471-47-7 is a valid CAS Registry Number.

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
