Check Digit Verification of cas no

The CAS Registry Mumber 198221-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,2,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 198221-75:
(8*1)+(7*9)+(6*8)+(5*2)+(4*2)+(3*1)+(2*7)+(1*5)=159
159 % 10 = 9
So 198221-75-9 is a valid CAS Registry Number.

Chiral Proton Catalysis: A Catalytic Enantioselective Direct Aza-Henry Reaction

Nugent, Benjamin M.,Yoder, Ryan A.,Johnston, Jeffrey N.

, p. 3418 - 3419 (2004)

Despite Nature's longstanding ability to use a proton, the most prevalent Lewis acid, to both activate and orient a substrate during an enantioselective reaction, this work represents the first example of this phenomenon outside of a protein. A chiral, no

The first enantioselective and diastereoselective catalytic nitro-Mannich reaction: A new entry to chiral vicinal diamines

Yamada,Moll,Shibasaki

, p. 980 - 982 (2007/10/03)

The first example of an enantioselective and diastereoselective catalytic nitro-Mannich reaction using a second-generation heterobimetallic complex has been developed. The corresponding nitro-Mannich products were obtained in up to 83% ee with a dr up to 7:1.
