Check Digit Verification of cas no
The CAS Registry Mumber 25781-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,8 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25781-90:
(7*2)+(6*5)+(5*7)+(4*8)+(3*1)+(2*9)+(1*0)=132
132 % 10 = 2
So 25781-90-2 is a valid CAS Registry Number.

-
, (2019/11/16)
A dyeing method is provided, which includes dyeing a dye to a fiber by a supercritical fluid, wherein the dye has a chemical structure of:R 1 is C1-6alkyl group, R 2 is C1-6alkyl group, each of R 3 is independently of H or C1-6alkyl group, and R 4 is a single bond or C1-6alkylene group. When R 4 is single bond, R 5 is. When R 4 is C1-6alkylene group, R 5 is H, Br, Cl, or. Each of R 6 is independently of H, Cl, Br, OCH3, or C1-6alkyl group.
