Check Digit Verification of cas no
The CAS Registry Mumber 156153-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,5 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156153-43:
(8*1)+(7*5)+(6*6)+(5*1)+(4*5)+(3*3)+(2*4)+(1*3)=124
124 % 10 = 4
So 156153-43-4 is a valid CAS Registry Number.

Synthesis of OSW-1 derivatives by site-selective acylation and their biological evaluation
Sakurai, Kaori,Takeshita, Tomoya,Hiraizumi, Masato,Yamada, Rika
, p. 6318 - 6321 (2014)
A strategy to site-selectively monoacylate an antitumor saponin OSW-1 was developed using an organotin reagent to rapidly access its derivatives that are useful as chemical probes. 4″-O-Acylated OSW-1 derivatives bearing a fluorophore, an alkyne tag, or biotin were prepared in good yields and were shown to maintain highly cytotoxic activity.
