1268839-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268839-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1268839-40:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*3)+(3*9)+(2*4)+(1*0)=202
202 % 10 = 2
So 1268839-40-2 is a valid CAS Registry Number.

Synthesis of triphenylsilyl[14C2]acetylene for use in a Sonogashira reaction
Elmore, Charles S.,Dorff, Peter N.
experimental part, p. 51 - 53 (2011/10/02)
Silylacetylenes are useful coupling partners for aromatic halides in the Sonogashira reaction and a C-14 labeled version of this useful synthon would allow ready access to a wide variety of arylalkynes. Ca14C 2 was converted to triph
