Check Digit Verification of cas no
The CAS Registry Mumber 1221171-77-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,1,7 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1221171-77:
(9*1)+(8*2)+(7*2)+(6*1)+(5*1)+(4*7)+(3*1)+(2*7)+(1*7)=102
102 % 10 = 2
So 1221171-77-2 is a valid CAS Registry Number.

METHOD FOR THE PREPARATION OF FUNCTIONALIZED TRIHALOMETHOXY SUBSTITUTED PYRIDINES
-
Page/Page column 31-32, (2010/04/28)
The present invention pertains to a process for the preparation of functionalized trihalomethoxypyridines of formula (I) comprising reacting hydroxypyridines with thiophosgene in the presence of a base; reacting the obtained chlorothionoformiates with elemental chlorine and finally converting trichloromethoxy pyridines to trihalomethoxy pyridines using a fluoride source.
