Check Digit Verification of cas no

The CAS Registry Mumber 1459161-09-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,9,1,6 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1459161-09:
(9*1)+(8*4)+(7*5)+(6*9)+(5*1)+(4*6)+(3*1)+(2*0)+(1*9)=171
171 % 10 = 1
So 1459161-09-1 is a valid CAS Registry Number.

, p. 9303 - 9308 (2013/10/01)

Organocatalytic Michael-aldol-dehydration domino reaction of 3-(1-hydroxyethylidene)benzofuran-2(3H)-ones and enones catalyzed by Cinchona-based primary amine has been developed. The desired chiral spirocyclic benzofuranones were obtained in excellent stereoselectivities (dr>20:1 and up to 96% ee) and moderate to excellent yields (up to 98%).
