74212-26-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74212-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,1 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74212-26:
(7*7)+(6*4)+(5*2)+(4*1)+(3*2)+(2*2)+(1*6)=103
103 % 10 = 3
So 74212-26-3 is a valid CAS Registry Number.

PHOSPHORYLATION OF NUCLEOSIDES USING MOLECULAR SIEVES AS ACID SCAVENGERS
Kohli, V.,Bloecker, H.,Koester, H.
, p. 501 - 502 (2007/10/02)
Molecular sieves (4 Angstroem) were used effectively to trap the generated hydrogen chloride during phosphorylation of protected nucleosides using phosphomonochloridates, thus preventing side reactions.
