1378808-36-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1378808-36-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,8,0 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1378808-36:
(9*1)+(8*3)+(7*7)+(6*8)+(5*8)+(4*0)+(3*8)+(2*3)+(1*6)=206
206 % 10 = 6
So 1378808-36-6 is a valid CAS Registry Number.

-

Page/Page column 14, (2008/06/13)

To provide a novel compound which satisfies characteristics required for an optical anisotropic material and which is excellent in durability against blue laser light, a liquid crystal composition containing the compound, an optical anisotropic material employing the liquid crystal composition and an optical element. A compound represented by the following formula (1): €?€?€?€?€?€?€?€?CH 2 =CR 1 -COO- (L) k -E 1 -E 2 -E 3 - (E 4 ) m - (E 5 ) n -R 2 €?€?€?€?€?(1) provided that the symbols in the formula have the following meanings: R 1 : a hydrogen atom or a methyl group; R 2 : a C 1-8 alkyl group; L: (CH 2 ) p O-, -(CH 2 ) q -, -Cy-COO- (Cy is a trans-1,4-cyclohexylene group), -Cy-OCO-, -E 6 -(CH 2 ) 2 -, -E 7 -CH 2 O- or -E 8 -O- (wherein each of p and q which are independent of each other, is an integer of from 2 to 8); E 1 , E 2 , E 3 , E 4 , E 5 , E 6 , E 7 , E 8 ,: each independently a 1,4-pheneylene group or a trans-1,4-cyclohexylene group (provided that at least one of E 1 , E 2 and E 3 is a trans-1,4-cyclohexylene group, and in a case where L is -Cy-OCO-, E 1 is a trans-1,4-cyclohexylene group), provided that the above 1,4-phenylene group and trans-1,4-cyclohexylene group may be such that a hydrogen atom bonded to a carbon atom in each group may be substituted by a fluorine atom, a chlorine atom or a methyl group; and k, m, n: each independently 0 or 1, provided that when k is 1 and L is -Cy-COO-, -Cy-OCO-, -E 6 -(CH 2 ) 2 -, -E 7 -CH 2 O- or -E 8 -O-, at least one of m and n is 0.
