134222-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134222-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,2 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134222-31:
(8*1)+(7*3)+(6*4)+(5*2)+(4*2)+(3*2)+(2*3)+(1*1)=84
84 % 10 = 4
So 134222-31-4 is a valid CAS Registry Number.

SYNTHESIS OF NUCLEOSIDE SULFONATES AND SULFONES
Musicki, Branislav,Widlanski, Theodore S.
, p. 1267 - 1270 (2007/10/02)
Sulfonate analogues of adenine, cytidine and guanine monophosphates have been synthesized for the first time.The synthesis of ribose-3-sulfonate, a synthesis of sulfonyl disaccharides and dinucleotides and an improved synthesis of a ribose 3-sulfone is also reported.
