Check Digit Verification of cas no

The CAS Registry Mumber 84542-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,4 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84542-26:
(7*8)+(6*4)+(5*5)+(4*4)+(3*2)+(2*2)+(1*6)=137
137 % 10 = 7
So 84542-26-7 is a valid CAS Registry Number.

Aldosterone Antagonists. 3. Synthesis and Activities of Steroidal 7α-(Alkoxycarbonyl)-15,16-methylene Spirolactones

Nickisch, Klaus,Bittler, Dieter,Laurent, Henry,Losert, Wolfgang,Nishino, Yukishige,et al.

, p. 509 - 513 (1990)

Several A- and D-ring substituted steroidal 7α-alkoxycarbonyl spirolactones were synthesized with the purpose of increasing the aldosterone antagonistic potency and reducing the endocrinological side effects relative to the standard drug spironolactone.It was found that the 15β,16β-methylene derivative 17 exhibited a 2-fold higher aldosterone antagonistic activity compared to either spironolactone or the 15,16-unsubstituted derivative 29 while showing remarkably reduced antiandrogenicity.
