Check Digit Verification of cas no

The CAS Registry Mumber 1621434-12-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,4,3 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1621434-12:
(9*1)+(8*6)+(7*2)+(6*1)+(5*4)+(4*3)+(3*4)+(2*1)+(1*2)=125
125 % 10 = 5
So 1621434-12-5 is a valid CAS Registry Number.

Synthesis of cyclobutenes and allenes by cobalt-catalyzed cross-dimerization of simple alkenes with 1,3-enynes

Nishimura, Akira,Tamai, Eri,Ohashi, Masato,Ogoshi, Sensuke

supporting information, p. 6613 - 6617 (2014/06/09)

Cobalt-catalyzed cross-dimerization of simple alkenes with 1,3-enynes is reported. A [2+2] cycloaddition reaction occurred, with alkenes bearing no allylic hydrogen, by reductive elimination of a η3-butadienyl cobaltacycle. On the other hand, a
