Check Digit Verification of cas no

The CAS Registry Mumber 3348-77-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3348-77:
(6*3)+(5*3)+(4*4)+(3*8)+(2*7)+(1*7)=94
94 % 10 = 4
So 3348-77-4 is a valid CAS Registry Number.

BUXUS ALKALOIDS. PART XI. THE SYNTHESIS OF CYCLOPROTOBUXINE-A (3β,20S-CHIRALITY) AND ITS TWO ISOMERIC ALKALOIDS WITH 3β,20R- AND 3α,20R- CONFIGURATION FROM LANOSTEROL.

Nakano, Tatsuhiko,Martin, Alfonso,Alonso, Miguel

, p. 2957 - 2968 (1991)

The synthesis of cycloprotobuxine-A (5), representative of Buxus alkaloids, and its two isomeric alkaloids with 3β,20R- and 3α,20R-configuration, from lanosterol, is described.In order to confirm the stereochemistries at C-3 and C-20 in these three alkaloids, the 3β-dimethylamino-(27) and the 3α-dimethylamino derivative (28) of cycloartanol (24) were also synthesised and their 1H and 13C n.m.r.spectra are discussed.
