Check Digit Verification of cas no
The CAS Registry Mumber 402-66-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 402-66:
(5*4)+(4*0)+(3*2)+(2*6)+(1*6)=44
44 % 10 = 4
So 402-66-4 is a valid CAS Registry Number.

-
Page/Page column 8, (2010/10/20)
To provide a method for producing a 3-substituted 2-chloro-5-fluoro-pyridine or its salt in high yield from a readily available material through a short process under mild reaction conditions using a reagent which is easy for handling and simple in the reaction operation. Namely, a method for producing the following compound (2) or its salt which comprises selectively reducing a chlorine atom at the 6-position of the following compound (1) or its salt, is provided. Further, a method for producing the following compound (4) or its salt which comprises substituting a Z1 group of the following compound (2) or its salt obtained by the reduction reaction, by a Z2 group, is provided. Here, Z1 is —CO2R1, etc., and R1 is a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, an aralkyl group or a cycloalkyl group. Z2 is a group different from Z1 and is —CO2R5, etc., and R5 is an alkyl group, an alkenyl group, an aryl group, an aralkyl group or a cycloalkyl group.
