18883-94-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18883-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,8 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18883-94:
(7*1)+(6*8)+(5*8)+(4*8)+(3*3)+(2*9)+(1*4)=158
158 % 10 = 8
So 18883-94-8 is a valid CAS Registry Number.

SIMPLE SYNTHESIS AND SEPARATION OF THE DIASTEREOMERS OF α-THIO ANALOGS OF RIBO- AND DEOXYRIBO- DI- AND TRIPHOSPHATES
Goody, R. S.,Isakov, M.
, p. 3599 - 3602 (1986)
Nucleoside 5'-O-(1-thiodi-) and triphosphates can be obtained in yields of up to 45percent directly from the nucleosides.Their diastereomers can be separated by preparative reversed phase chromatography.
