Check Digit Verification of cas no

The CAS Registry Mumber 189077-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189077-97:
(8*1)+(7*8)+(6*9)+(5*0)+(4*7)+(3*7)+(2*9)+(1*7)=192
192 % 10 = 2
So 189077-97-2 is a valid CAS Registry Number.

Synthesis of a scalemic β-amino disulfide from (S)-phenylglycine and (R)-styrene oxide and use as a catalyst in enantioselective additions of diethylzinc to aldehydes

Fulton, David A.,Gibson, Colin L.

, p. 2019 - 2022 (1997)

Two routes to the novel scalemic β-amino disulfide 7 have been developed from (S)- phenylglycine and (R)-styrene oxide. The β-amino disulfide 7 was used as a catalyst in the enantioselective addition of diethylzine to aldehydes providing (R)-secondary alcohols in 39-80% ee.
