119005-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119005-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,0 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 119005-68:
(8*1)+(7*1)+(6*9)+(5*0)+(4*0)+(3*5)+(2*6)+(1*8)=104
104 % 10 = 4
So 119005-68-4 is a valid CAS Registry Number.

SOLID PHASE SYNTHESIS OF OLIGONUCLEOTIDES CONTAINING 3'-THIOTHYMIDINE
Cosstick, Richard,Vyle, Joseph S.
, p. 4693 - 4696 (2007/10/02)
A 5'-O-monomethoxytritylthymidine-3'-S-thiophosphoramidite (3) has been used to prepare oligodeoxynucleotides containing 3'-thiothymidine on a solid phase support.The intermediate thiophosphites are most efficiently oxidised using tetrabutylammonium periodate.
