40339-29-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40339-29-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,3 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40339-29:
(7*4)+(6*0)+(5*3)+(4*3)+(3*9)+(2*2)+(1*9)=95
95 % 10 = 5
So 40339-29-5 is a valid CAS Registry Number.

Electron transfer and contact ion pair formation, 45 [1, 2] structural changes on single electron reduction of tetraphenylbutatriene to its radical anion and on twofold deprotonation of tetraphenylbutyne-2 to the tetraphenylbutatriene dianion

Bock,Arad,Naether,Goebel,John,Baur

, p. 1381 - 1390 (2007/10/03)

Tetraphenylbutatriene is reduced under aprotic conditions to its ESR/ENDOR-spectroscopically characterized radical anion and to its dianion, with both electron transfers quasi-reversible according to cyclovoltammetric measurements. The alkali cation salts
