Check Digit Verification of cas no

The CAS Registry Mumber 129817-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,1 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129817-19:
(8*1)+(7*2)+(6*9)+(5*8)+(4*1)+(3*7)+(2*1)+(1*9)=152
152 % 10 = 2
So 129817-19-2 is a valid CAS Registry Number.

The Reaction of Wittig Reagents with Selenium. Formation of Selenoaldehydes

Okuma, Kentaro,Komiya, Yasuo,Kaneko, Isao,Tachibana, Yuji,Iwata, Eiji,Ohta, Hiroshi

, p. 1653 - 1657 (2007/10/02)

The reaction of Wittig reagents with elemental selenium gave the corresponding selenoaldehydes which further reacted with other Wittig reagents to give the corresponding dimeric olefins in good yields.The selenoaldehydes formed afforded corresponding adducts by the reaction with dienes.These selenoaldehydes obtained by retro Diels-Alder reaction were also found to react with Wittig reagents to give the corresponding olefins in good yields.
