76540-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76540-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,4 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 76540-23:
(7*7)+(6*6)+(5*5)+(4*4)+(3*0)+(2*2)+(1*3)=133
133 % 10 = 3
So 76540-23-3 is a valid CAS Registry Number.

, p. 177 - 196 (2007/10/02)
5-Alkyl(cycloalkyl)-2'-deoxyuridines VIa-VIf were synthesised in high yields by condensation of the corresponding silylated bases with 2-deoxy- 3,5-di-O-p-toluoyl-D-erythro-pentosyl chloride in chloroform and subsequent deblocking with sodium methoxide in
