81190-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81190-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81190-89:
(7*8)+(6*1)+(5*1)+(4*9)+(3*0)+(2*8)+(1*9)=128
128 % 10 = 8
So 81190-89-8 is a valid CAS Registry Number.

4-substituted-5(3)-carbamoyl-3(5)-(2-deoxy-β-D- ribofuranosyl)pyrazoles. Application of palladium catalyzed glycal coupling methodology to the synthesis of pyrazofurin analogs

Erion, Mark D.,Rydzewski, Robert M.

, p. 315 - 337 (2007/10/03)

Analogs of the C-nucleoside pyrazofurin were prepared in 7-9 steps using a key Pd(0)-catalyzed coupling reaction between protected iodopyrazoles 6a and 6b and glycal 8 to form the glycosyl bond. Conditions for this reaction were improved from those previously described for related reactions in order to maximize product yields and eliminate the need for triphenylarsine.
