Check Digit Verification of cas no

The CAS Registry Mumber 116538-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,3 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 116538-60:
(8*1)+(7*1)+(6*6)+(5*5)+(4*3)+(3*8)+(2*6)+(1*0)=124
124 % 10 = 4
So 116538-60-4 is a valid CAS Registry Number.

Synthetic Application of Tris(methylthio)methyl Salts. An Efficient Route to Trithioorthocarboxylic Esters from Strongly Activated Aromatic and Heteroaromatic Systems

Barbero, Margherita,Cadamuro, Silvano,Degani, Iacopo,Fochi, Rita,Gatti, Antonella,Regondi, Valeria

, p. 22 - 25 (2007/10/02)

Nine trithioorthocarboxylic esters were synthesized by reaction of tris(methylthio)methyl methyl sulfate or tetrafluoroborate with electron-rich aromatic and heteroaromatic compounds, i.e.N,N-dialkylarylamines, pyrroles, and indoles.The new procedure is simple and offers the following advantages: easy preparation of reagents; mild reaction condition; possibility to introduce two tris(methylthio)methyl groups into the same ring, good to excellent yields.
