Check Digit Verification of cas no

The CAS Registry Mumber 128702-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,0 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128702-33:
(8*1)+(7*2)+(6*8)+(5*7)+(4*0)+(3*2)+(2*3)+(1*3)=120
120 % 10 = 0
So 128702-33-0 is a valid CAS Registry Number.

APPLICATION OF 4-AZIDOBENZYL GROUP TO PROTECTION OF HYDROXYL FUNCTIONS

Fukase, Koichi,Hashida, Manabu,Kusumoto, Shoichi

, p. 3557 - 3558 (2007/10/02)

The 4-azidobenzyl ether can be readily formed and cleaved either by direct oxidation with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) or by oxidation after conversion to the 4-aminobenzyl ether or the corresponding iminophosphorane derivative.In the latter two-step cleavage methods the azidobenzyl group is removed in preference to the 4-methoxybenzyl (MPM) group, whereas the MPM group can be selectively removed by the direct DDQ oxidation.
