Check Digit Verification of cas no
The CAS Registry Mumber 77638-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77638-64:
(7*7)+(6*7)+(5*6)+(4*3)+(3*8)+(2*6)+(1*4)=173
173 % 10 = 3
So 77638-64-3 is a valid CAS Registry Number.

REACTIONS AND SYNTHETIC APPLICATIONS OF β-KETO SULFOXIDES IX. SYNTHESIS OF 5-METHYLTHIO AND 5-METHOXY ANALOGS OF ELLIPTICINE

A β-keto sulfoxide (9) derived from ethyl indolebutyrate (8) and FAMSO was cyclized to a 2-keto-1,2,3,4-tetrahydrocarbazole derivative (10).After introduction of an acetic ester at the carbonyl group to give 11, its aromatization gave a 1-methylthiocarbazole (12), followed by construction of a pyridine ring to yield efficiently 5-methylthioellipticine (6).Compound 11 was quite easily hydrolyzed to a 1-keto derivative (18), which was aromatized and then converted to 5-methoxyellipticine (7).
