Check Digit Verification of cas no

The CAS Registry Mumber 1167413-22-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,7,4,1 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1167413-22:
(9*1)+(8*1)+(7*6)+(6*7)+(5*4)+(4*1)+(3*3)+(2*2)+(1*2)=140
140 % 10 = 0
So 1167413-22-0 is a valid CAS Registry Number.

Synthesis of optically active conjugated polymers bearing m-terphenylene moieties by acetylenic coupling polymerization: Chiral aggregation and optical properties of the product polymers

Miyagi, Yu,Sogawa, Hiromitsu,Shiotsuki, Masashi,Sanda, Fumio

, p. 1594 - 1603 (2014/04/03)

The acetylenic coupling polymerization of D-hydroxyphenylglycine-derived m-terphenylene diynes 1-5 using Pd/Cu catalyst gave the corresponding polymers [poly(1)-poly(5)] with Mn = 12 000-60 000 in 53-89% yields. The polymers were soluble in THF
