Check Digit Verification of cas no

The CAS Registry Mumber 1443523-50-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,5,2 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1443523-50:
(9*1)+(8*4)+(7*4)+(6*3)+(5*5)+(4*2)+(3*3)+(2*5)+(1*0)=139
139 % 10 = 9
So 1443523-50-9 is a valid CAS Registry Number.

Ruthenium catalyzed hydroaminoalkylation of isoprene via transfer hydrogenation: Byproduct-free prenylation of hydantoins

Schmitt, Daniel C.,Lee, Jungyong,Dechert-Schmitt, Anne-Marie R.,Yamaguchi, Eiji,Krische, Michael J.

supporting information, p. 6096 - 6098 (2013/07/11)

The ruthenium catalyst derived from Ru3(CO)12 and triphos [Ph2P(CH2CH2PPh2) 2] promotes the direct C-C coupling of isoprene with aryl substituted hydantoins 1a-1f at the diene C4-position to furnish products of n-prenylation 2a-2f. A mechanism involving hydantoin dehydrogenation followed by diene-imine oxidative coupling to furnish a transient aza-ruthencyclopentene is proposed.
