Check Digit Verification of cas no

The CAS Registry Mumber 1380572-67-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,5,7 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1380572-67:
(9*1)+(8*3)+(7*8)+(6*0)+(5*5)+(4*7)+(3*2)+(2*6)+(1*7)=167
167 % 10 = 7
So 1380572-67-7 is a valid CAS Registry Number.

A new protecting group and linker for uridine ureido nitrogen

Wang, Yong,Kurosu, Michio

, p. 4797 - 4804 (2012/08/08)

(2,6-Dichloro-4-methoxyphenyl)(2,4,6-trichlorophenyl) methoxymethyl chloride [1, monomethoxydiph-enylmethoxylmethyl chloroide (MDPM-Cl)] shows a significant relative stability and 1 reacts with uridine ureido nitrogen in the presence of DBU to form the corresponding protected uridine 8 in 95% yield. The MDPM-protected uridines are stable to a wide variety of conditions utilized for the synthesis of analogs of capuramycin and muraymycins. Significantly, the MDPM protecting group can conveniently be deprotected by using 30% TFA in CH 2Cl2. In addition, polymer-bound MDPM-Cl 23 is useful for immobilization of uridine derivatives.
