Check Digit Verification of cas no

The CAS Registry Mumber 1026620-42-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,6,2 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1026620-42:
(9*1)+(8*0)+(7*2)+(6*6)+(5*6)+(4*2)+(3*0)+(2*4)+(1*2)=107
107 % 10 = 7
So 1026620-42-7 is a valid CAS Registry Number.

Electronic substituent effects on the EPR-spectral D parameter of trimethylenemethane (TMM) triplet diradicals compared with localized cyclopentane-1,3-diyls

Abe, Manabu,Adam, Waldemar

, p. 1063 - 1068 (2007/10/03)

The EPR-spectral D parameter for a series of aryl-substituted trimethylenemethane (TMM) derivatives 2a-g has been determined in a 2-methyltetrahydrofuran (MTHF) matrix at 77 K. Although the substituent effects on the D parameter are relatively small compa
