Check Digit Verification of cas no

The CAS Registry Mumber 1416000-55-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,0,0 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1416000-55:
(9*1)+(8*4)+(7*1)+(6*6)+(5*0)+(4*0)+(3*0)+(2*5)+(1*5)=99
99 % 10 = 9
So 1416000-55-9 is a valid CAS Registry Number.

Application of flow photochemical bromination in the synthesis of a 5-bromomethylpyrimidine precursor of rosuvastatin: Improvement of productivity and product purity

Sterk, Damjan,Jukic, Marko,Casar, Zdenko

, p. 145 - 151 (2013)

In this report we present a flow photochemical bromination of a 5-methyl-substituted pyrimidine precursor of rosuvastatin. The study demonstrated that the reaction productivity can be increased markedly with a flow-mode approach compared to a batch-mode synthesis. Indeed, reaction times can be significantly shortened from a range of hours to a range of minutes. Moreover, in addition to process intensification, the study demonstrated that significantly lower overall levels of side products are obtained when photochemical bromination is conducted in a flow mode.
