Check Digit Verification of cas no

The CAS Registry Mumber 136386-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,8 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136386-45:
(8*1)+(7*3)+(6*6)+(5*3)+(4*8)+(3*6)+(2*4)+(1*5)=143
143 % 10 = 3
So 136386-45-3 is a valid CAS Registry Number.

A synthesis of 5'-O-acryloyl-5-fluorouridine by use of p-methoxybenzyl group as an N3-imide protecting group of 5-fluorouridine

Akiyama,Takesue,Kumegawa,Nishimoto,Ozaki

, p. 2266 - 2269 (1991)

5'-O-Acryloyl-5-fluorouridine was preparedd by use of p-methoxybenzyl (PMB) group as an N3-imide protecting group of 5-fluorouridine. PMB group was introduced chemoselectively by use of N,N-diisopropylethylamine or DBU as a base. A new deprotection method was developed by means of AlCl3-anisole system at room temperature.
