Check Digit Verification of cas no

The CAS Registry Mumber 1356114-34-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,1,1 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1356114-34:
(9*1)+(8*3)+(7*5)+(6*6)+(5*1)+(4*1)+(3*4)+(2*3)+(1*4)=135
135 % 10 = 5
So 1356114-34-5 is a valid CAS Registry Number.

Enantioselective Desymmetrization of 3-Substituted Oxetanes: An Efficient Access to Chiral 3,4-Dihydro-2H-1,4-benzoxazines

Bhosale, Viraj A.,Nigríni, Martin,Dra?ínsky, Martin,Císa?ová, Ivana,Vesely, Jan

supporting information, p. 9376 - 9381 (2021/12/09)

Herein, we describe a versatile transition metal/oxidant free synthesis of the chiral 2H-1,4-benzoxazines through chiral phosphoric acid (CPA) catalyzed enantioselective desymmetrization of prochiral oxetanes (30 examples) in up to 99% yield and 99% enantioselectivity under mild reaction conditions. The reported strategy not only complements the conventional 2H-1,4-benzoxazine synthetic strategies but also provides access to key intermediates of therapeutic candidates, i.e., prostaglandin D2 receptor antagonist and M1 positive allosteric modulator (PAM) compound VU0486846.
