Check Digit Verification of cas no

The CAS Registry Mumber 1551093-24-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,1,0,9 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1551093-24:
(9*1)+(8*5)+(7*5)+(6*1)+(5*0)+(4*9)+(3*3)+(2*2)+(1*4)=143
143 % 10 = 3
So 1551093-24-3 is a valid CAS Registry Number.

supporting information, p. 1057 - 1060 (2014/02/14)

An enantioselective oxa-Michael addition of oximes to β-CF 3-β-disubstituted nitroalkenes catalyzed by a chiral bifunctional cinchona alkaloid-based thiourea has been developed. A variety of trifluoromethylated oxime ethers possessing a tetrasubstituted carbon stereocenter were obtained in good yields with high enantioselectivities. The Royal Society of Chemistry.
