Check Digit Verification of cas no

The CAS Registry Mumber 504440-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,4,4,4 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 504440-55:
(8*5)+(7*0)+(6*4)+(5*4)+(4*4)+(3*0)+(2*5)+(1*5)=115
115 % 10 = 5
So 504440-55-5 is a valid CAS Registry Number.

, p. 867 - 872 (2002)

We have developed a two-step method for synthesis of 3-(hetarylthio)-1-propynyl(trimethyl)silanes from thiols in a phase-transfer catalysis system HC≡CCH2Br-solid K2CO3-18-crown-6-toluene followed by reaction with n-BuLi-Me3SiCl in ether or THF. We have observed that 3-[1,3-bis(trimethylsilyl)-2-propynyl] thioindole displays high cytotoxicity in HT-1080 and MG-22A tumor cell lines.
