Check Digit Verification of cas no

The CAS Registry Mumber 1228273-12-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,7 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1228273-12:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*7)+(3*3)+(2*1)+(1*2)=138
138 % 10 = 8
So 1228273-12-8 is a valid CAS Registry Number.

Synthesis and biological evaluation of antitumor-active γ-butyrolactone substituted betulin derivatives

Csuk, René,Barthel, Alexander,Schwarz, Stefan,Kommera, Harish,Paschke, Reinhard

, p. 2549 - 2558 (2010)

The plant triterpenes betulin and betulinic acid (BA) are triterpenes featuring interesting pharmacological properties. Starting from substituted betulinic aldehydes, we used them as lead structures for the synthesis of several γ-butyrolactones and butenolides. Their antitumor activity was examined for 15 cancer cell lines using a SRB-assay and their apoptotic action was documented by trypan-blue test and DNA laddering. Several compounds revealed a higher activity than betulinic acid.
