Check Digit Verification of cas no
The CAS Registry Mumber 199982-02-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,9,8 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 199982-02:
(8*1)+(7*9)+(6*9)+(5*9)+(4*8)+(3*2)+(2*0)+(1*2)=210
210 % 10 = 0
So 199982-02-0 is a valid CAS Registry Number.

-
Paragraph 0051; 0053, (2021/06/13)
The invention discloses a synthesis method of 4-alkyl biphenyl acetylene. The synthesis method comprises the following steps: carrying out catalytic hydrogenation reaction on 4-alkyl diketone to obtain 4-alkyl biphenyl; then reacting the 4-alkyl biphenyl with halogen to obtain 4-halogen-4 '-alkyl biphenyl; and allowing 4-halo-4 '-alkyl biphenyl and an ethynylation reagent to be subjected to a coupling reaction to obtain a compound shown in a formula (IV) under the action of alkali. The method creatively adopts a palladium catalyst and lewis acid combined catalytic system to carry out deoxidation reaction on 4-alkyl diketone, and has good selectivity and high yield; in addition, hydrogen is used as a hydrogen source, a byproduct is only water, and the method is environment-friendly.
