Check Digit Verification of cas no

The CAS Registry Mumber 134129-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,2 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134129-56:
(8*1)+(7*3)+(6*4)+(5*1)+(4*2)+(3*9)+(2*5)+(1*6)=109
109 % 10 = 9
So 134129-56-9 is a valid CAS Registry Number.

REACTIONS OF PHOSPHONIUM YLIDES ON THIA- AND OXADIAZOLE DERIVATIVES

Fahmy, A. A.,Hafez, T. S.,Boulos, L. S.

, p. 219 - 223 (2007/10/02)

Phosphonium ylides 2(a,b) add to 2-thiono-5-pyridyl 1,3,4-thiadiazole (1a) to give the same ylid-phosphorane adduct 3a.While the same ylides did not affect on 2-thiono-5-pyridyl (1b).On the other hand addition of fluorenylidenetriphenylphosphorane (3c) gave the episulphides (3b) and (3c), respectively.The given structures were based upon analytical, chemical and spectroscopic results.
