Check Digit Verification of cas no

The CAS Registry Mumber 1267248-41-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,2,4 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1267248-41:
(9*1)+(8*2)+(7*6)+(6*7)+(5*2)+(4*4)+(3*8)+(2*4)+(1*1)=168
168 % 10 = 8
So 1267248-41-8 is a valid CAS Registry Number.

, (2012/07/03)

Provided are an organic EL device material capable of reducing the driving voltage of an organic EL device and increasing the lifetime of the device as compared with a conventional organic EL device material, specifically an aromatic amine derivative represented by N(Ara)(Arb)(Arc), and an organic EL device using the material. [Ara is represented by the formula (II). (In the formula (II): La represents a single bond or an arylene group; R1 to R4 each represent an alkyl group, an aryl group, or the like, and R3's or R4's, or R3 and R4 may be bonded to each other to form a ring; and o represents 0 to 3 and p represents 0 to 4.) Arb is represented by the formula (III). (in the formula (III), X represents NRa, O, or S, and Ra and R5 to R7 each represent an alkyl group, an aryl group, or the like, and R5's, R6's, or R7's adjacent to each other, or R5 and R6 may be bonded to each other to form a ring; n represents 2 to 4 when X represents NRa, and represents 0 to 4 when X represents O or S; and q represents 0 to 3, r and s each independently represent 0 to 4.) Arc represents an aryl group, or is represented by the formula (III).]
