Check Digit Verification of cas no

The CAS Registry Mumber 1403649-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,6,4 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1403649-85:
(9*1)+(8*4)+(7*0)+(6*3)+(5*6)+(4*4)+(3*9)+(2*8)+(1*5)=153
153 % 10 = 3
So 1403649-85-3 is a valid CAS Registry Number.

Organocatalytic asymmetric direct Csp3 -H functionalization of ethers: A highly efficient approach to chiral spiroethers

, p. 8811 - 8815 (2012/10/08)

Spiro compounds: An organocatalytic asymmetric method for the C sp 3=H functionalization of the α position of racemic cyclic ethers has been developed. The transformation, mediated by catalytic amounts of an imidazolidinone and strong acid, involves a tandem 1,5-hydride transfer/cyclization and provides access to a structurally diverse series of chiral spiroethers with high levels of enantioselectivity (see scheme).
