337973-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 337973-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,9,7 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 337973-20:
(8*3)+(7*3)+(6*7)+(5*9)+(4*7)+(3*3)+(2*2)+(1*0)=173
173 % 10 = 3
So 337973-20-3 is a valid CAS Registry Number.

Synthesis of benzofuranofuran derivatives: Model of natural products

Donate,Da Silva,Valdo,Da Silva,Aleman

, p. 141 - 150 (2001)

Several benzofuranofuran derivatives were synthesized employing intramolecular cycloaddition reactions of ketenes with alkenes. (Alkenyloxy)ketenes, prepared from the tosylate by treatment with triethylamine, easily undergo intramolecular [2 + 2] cycloadd
