Check Digit Verification of cas no

The CAS Registry Mumber 1227507-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,5,0 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1227507-28:
(9*1)+(8*2)+(7*2)+(6*7)+(5*5)+(4*0)+(3*7)+(2*2)+(1*8)=139
139 % 10 = 9
So 1227507-28-9 is a valid CAS Registry Number.

Synthesis and molecular structure of silole derivatives bearing functional groups on silicon: 1,1-organoboration of dialkynylsilanes

Khan, Ezzat,Bayer, Stefan,Kempe, Rhett,Wrackmeyer, Bernd

experimental part, p. 4416 - 4424 (2010/03/04)

Various dialkynylsilanes bearing Si-H or SiCl functions in addition to the alkynyl groups react with an excess of triethylborane after heating at 100-110 °C for several days via slow intermolecular 1,1-ethylboration followed by fast intramolecular 1,1-vin
