Check Digit Verification of cas no

The CAS Registry Mumber 128538-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128538-22:
(8*1)+(7*2)+(6*8)+(5*5)+(4*3)+(3*8)+(2*2)+(1*2)=137
137 % 10 = 7
So 128538-22-7 is a valid CAS Registry Number.

SN2'Substitutions of 1,3-Dichloropropenes with the Functionalized Copper-Zinc Reagents RCu(CN)ZnX

Chen, Huai Gu,Gage, Jennifer L.,Barrett, Stephen D.,Knochel, Paul

, p. 1829 - 1832 (2007/10/02)

The addition of benzenesulfenyl (or benzeneselenyl) chlorides to propargylic chlorides affords regio- and stereospecifically (E)-1,3-dichloro-2-phenylsulfenyl (or phenylselenyl) propenes (2a-c).These new reagents were found to react with excellent SN2'selectivity with the highly functionalized copper-zinc reagents RCu(CN)ZnX, affording polyfunctional vinylic-thioethers or -selenides of type 3.The acidic hydrolysis of 3 furnishes symmetrical ketones in good yields.
