Check Digit Verification of cas no

The CAS Registry Mumber 1440095-48-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,0,9 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1440095-48:
(9*1)+(8*4)+(7*4)+(6*0)+(5*0)+(4*9)+(3*5)+(2*4)+(1*8)=136
136 % 10 = 6
So 1440095-48-6 is a valid CAS Registry Number.

Absolute stereochemical assignment of SCH 71450, a selective dopamine D4 receptor antagonist, through enantioselective epimer synthesis

Wu, Hsin-Pei,Lu, Tai-Ni,Hsu, Nai-Yun,Chang, Che-Chien

, p. 2898 - 2905 (2013/07/05)

The absolute stereochemical assignment of SCH 71450, a selective dopamine D4 receptor antagonist, has been successfully confirmed through enantioselective epimer synthesis. An allyl substituent on the p-hydroxybenzyl group was demonstrated to be an appropriate protecting group for Noyori Ru-catalyzed asymmetric transfer hydrogenation of the imine derivative. The construction of the sugar moiety involved a β-glycosylation reaction assisted by neighboring group participation. By comparison with literature data, the absolute stereochemistry at the C-1 carbon on the tetrahydroisoquinoline core has been assigned the S configuration. Copyright
