Check Digit Verification of cas no

The CAS Registry Mumber 1621003-22-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,0,0 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1621003-22:
(9*1)+(8*6)+(7*2)+(6*1)+(5*0)+(4*0)+(3*3)+(2*2)+(1*2)=92
92 % 10 = 2
So 1621003-22-2 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of 4-nitropyrazolidines: An access to optically active 1,2,3-triamines

Lykke, Lennart,Carlsen, Bj?rn Drei?,Rambo, Raoní Scheibler,J?rgensen, Karl Anker

supporting information, p. 11296 - 11299 (2014/09/17)

The first catalytic enantio- and diastereoselective synthesis of 4-nitropyrazolidines is presented. Asymmetric hydrogen-bonding activation of nitro-olefins facilitated the 1,3-dipolar cycloaddition with hydrazones, affording optically active 4-nitropyrazo
