Check Digit Verification of cas no

The CAS Registry Mumber 1053264-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,3,2,6 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1053264-01:
(9*1)+(8*0)+(7*5)+(6*3)+(5*2)+(4*6)+(3*4)+(2*0)+(1*1)=109
109 % 10 = 9
So 1053264-01-9 is a valid CAS Registry Number.

2-(Prenyloxymethyl)benzoyl (POMB) group: a new temporary protecting group removable by intramolecular cyclization

Vatèle, Jean-Michel

, p. 10921 - 10929 (2008/02/12)

2-(Prenyloxymethyl)benzoates can be prepared from alcohols and readily available 2-(prenyloxymethyl)benzoic acid by standard acylation techniques or by Mitsunobu reaction with inversion of configuration. The POMB group can be cleaved first by oxidative removal of the prenyl group with DDQ followed by lactonization with expulsion of the alcohol catalyzed by Yb(OTf)3. These reaction conditions are compatible with the presence of a large number of common protecting groups.
