Check Digit Verification of cas no

The CAS Registry Mumber 507243-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,7,2,4 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 507243-31:
(8*5)+(7*0)+(6*7)+(5*2)+(4*4)+(3*3)+(2*3)+(1*1)=124
124 % 10 = 4
So 507243-31-4 is a valid CAS Registry Number.

Indium-mediated reformatsky-type reaction of β-aminovinyl chlorodifluoromethyl ketones with heteroaryl aldehydes

Medebielle, Maurice,Onomura, Osamu,Keirouz, Robert,Okada, Etsuji,Yano, Hirokazu,Terauchi, Terukazu

, p. 2601 - 2608 (2002)

Indium can efficiently mediate the Reformatsky-type reaction between some β-aminovinyl chlorodifluoromethyl ketones and a series of heteroaryl aldehydes, to afford the corresponding difluoromethylene compounds in good to high yields.
