67898-71-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67898-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,9 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67898-71:
(7*6)+(6*7)+(5*8)+(4*9)+(3*8)+(2*7)+(1*1)=199
199 % 10 = 9
So 67898-71-9 is a valid CAS Registry Number.

A BRIEF AND REGIOSPECIFIC SYNTHESIS OF THE LATE-STAGE INTERMEDIATE TO 11-DEOXYANTHRACYCLINONES

Tamura, Y.,Akai, S.,Sasho, M.,Kita, Y.

, p. 1167 - 1170 (1984)

The late-stage intermediate (8) to 11-deoxyanthracyclinones has been prepared by a strong base induced cycloaddition of 6-oxo-5,6,7,8-tetrahydrohomophthalic anhydride 1,2-ethanediyl acetal (9) to 3-bromojuglone methyl ether (1O).
