Check Digit Verification of cas no

The CAS Registry Mumber 1352211-98-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,2,1 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1352211-98:
(9*1)+(8*3)+(7*5)+(6*2)+(5*2)+(4*1)+(3*1)+(2*9)+(1*8)=123
123 % 10 = 3
So 1352211-98-3 is a valid CAS Registry Number.

Novel thermolabile protecting groups with higher stability at ambient temperature

Chmielewski, Marcin K.

supporting information; experimental part, p. 666 - 669 (2012/02/15)

Novel thermolabile hydroxyl protecting groups of increased thermostability are proposed. The stability of these groups at different temperatures ranges has been determined. The 2-pyridyl-N-(2,4-difluorobenzyl)aminoethyl unit was selected as stable at ambient temperature and very labile at increased temperature. The half-life times for the best groups were established. Application of this chemistry to the protection of different hydroxyl groups of thymidine was also demonstrated.
