98889-57-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98889-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,8 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98889-57:
(7*9)+(6*8)+(5*8)+(4*8)+(3*9)+(2*5)+(1*7)=227
227 % 10 = 7
So 98889-57-7 is a valid CAS Registry Number.

Synthesis of C-5 and N-3 Arenesulfenyl Uridines. Preparation and Properties of a New Class of Uracil Protecting Group

Welch, C. J.,Bazin, H.,Heikkila, J.,Chattopadhyaya, J.

, p. 203 - 212 (2007/10/02)

The nature and position of the ring substituent of an arenesulfenyl chloride control the regiospecific formation of either a C-5 substituted product, as in compounds 3a-3d, or a N-3 substituted product, as in compound 2a-2c.Arenesulfenyl groups have been subsequently found to successfully protect the urethane function of the residue as exemplified by teh synthesis of 2'-O-methyl uridine and oligoribonucleotide building blocks.
