Check Digit Verification of cas no

The CAS Registry Mumber 136981-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,8 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136981-87:
(8*1)+(7*3)+(6*6)+(5*9)+(4*8)+(3*1)+(2*8)+(1*7)=168
168 % 10 = 8
So 136981-87-8 is a valid CAS Registry Number.

Addition of Racemic Alkoxyallylstannanes to an Enantiomerically Pure 2-Methoxyoxazolidine: An Example of Combined Mutual Diastereoface Selection and Kinetic Resolution

Bernardi, Anna,Poli, Giovanni,Scolastico, Carlo,Zanda, Matteo

, p. 6961 - 6963 (1991)

The BF3*Et2O-promoted addition of racemic α- and γ-alkoxyallylstannanes 2 or 3 to the 2-methoxyoxazolidine 1 afforded adducts 4 and 5 in diastereomeric ratios up to 95:5 accompanied by enantioenriched γ-stannanes (R)-3.This behavior is consistent with a f
