Check Digit Verification of cas no

The CAS Registry Mumber 1268250-86-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,2,5 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1268250-86:
(9*1)+(8*2)+(7*6)+(6*8)+(5*2)+(4*5)+(3*0)+(2*8)+(1*6)=167
167 % 10 = 7
So 1268250-86-7 is a valid CAS Registry Number.

-

Paragraph 0047; 0050; 0088; 0089, (2017/03/24)

PROBLEM TO BE SOLVED: To provide an industrial manufacturing method of efficiently manufacturing polysubstituted cyclic azine compound with high purity.SOLUTION: There is provided a method of manufacturing polysubstituted cyclic azine compound having {(the mol number of a transition metal in a transition metal compound)÷(the mol number of a compound represented by the general formula (2)) of 0.00001 to 0.009 in a coupling reaction of the component represented by the general formula (2) and a compound represented by the general formula (3) in a presence of the transition metal compound, a phosphine compound and a base. (2), where Ar, Arand Arrepresent a monovalent substituent having 1 to 40 carbon atoms, Xrepresents a chlorine atom, a bromine atom or an iodine atom. Y represents CH or a nitrogen atom. (3), where Arrepresents a monovalent substituent having 1 to 40 carbon atoms, Rrepresents a hydrogen atom, an alkyl group or a phenyl group.
