Check Digit Verification of cas no

The CAS Registry Mumber 436802-18-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,6,8,0 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 436802-18:
(8*4)+(7*3)+(6*6)+(5*8)+(4*0)+(3*2)+(2*1)+(1*8)=145
145 % 10 = 5
So 436802-18-5 is a valid CAS Registry Number.

Synthesis of some steroidal oxazolines

Woelfling, Janos,Mernyak, Erzsebet,Sebok, Melinda,Schneider, Gyula

, p. 1831 - 1840 (2001)

Steroidal oxazolines 4a-4d and 5a-5f were synthesized. The acid-catalyzed reactions of 21-azido-20-hydroxy- and 21-hydroxy-20-azidosteroids with substituted aromatic aldehydes led to the formation of androst-5-en-3β-ols substituted in position 17β with oxazoline residues.
