Check Digit Verification of cas no

The CAS Registry Mumber 1380076-98-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,0,7 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1380076-98:
(9*1)+(8*3)+(7*8)+(6*0)+(5*0)+(4*7)+(3*6)+(2*9)+(1*8)=161
161 % 10 = 1
So 1380076-98-1 is a valid CAS Registry Number.

Enantioselective synthesis of 2-amino-4H-pyrans via the organocatalytic cascade reaction of malononitrile and α-substituted chalcones

Hu, Zhi-Peng,Wang, Wei-Juan,Yin, Xiao-Gang,Zhang, Xue-Jing,Yan, Ming

experimental part, p. 461 - 467 (2012/07/28)

An organocatalytic cascade reaction of malononitrile and α-substituted chalcones has been developed for the synthesis of chiral multisubstituted 2-amino-4H-pyran derivatives. A series of chiral primary/tertiary amines and cinchona alkaloids were examined as the catalysts. Quinine was found to be the most efficient catalyst in the absence of any additive. The α-substitutents of the chalcones had a siginificant effect on the yield and the enantioselectivity. A number of multisubstituted 2-amino-4H-pyrans were obtained in excellent yields and enantioselectivities.
