Check Digit Verification of cas no

The CAS Registry Mumber 916767-00-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,7,6 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 916767-00:
(8*9)+(7*1)+(6*6)+(5*7)+(4*6)+(3*7)+(2*0)+(1*0)=195
195 % 10 = 5
So 916767-00-5 is a valid CAS Registry Number.

Practical synthesis of new chiral cis-phthalazinones with potential for high phosphodiesterase(PDE4) inhibitory activity

Van Dang, Tinh,Jin, Chung Kenn,Miyamoto, Motoyuki,Ikee, Yoshifumi,Masuda, Takashi,Sano, Shigeki,Shiro, Motoo,Nagao, Yoshimitsu

, p. 2133 - 2144 (2008/01/27)

New chiral cis-tetrahydrophthalazinones were synthesized directly from the corresponding chiral (4R)- and (4S)-isopropyl-1,3-thiazolidine-2-thione amides in one-pot reaction involving mild aminolysis with hydrazine monohydrate followed by intramolecular c
