Check Digit Verification of cas no

The CAS Registry Mumber 80396-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,9 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80396-08:
(7*8)+(6*0)+(5*3)+(4*9)+(3*6)+(2*0)+(1*8)=133
133 % 10 = 3
So 80396-08-3 is a valid CAS Registry Number.

Catalytic Asymmetric 1,6-Conjugate Addition of para-Quinone Methides: Formation of All-Carbon Quaternary Stereocenters

Wang, Zhaobin,Wong, Yuk Fai,Sun, Jianwei

supporting information, p. 13711 - 13714 (2015/11/11)

Described herein is a general and mild catalytic asymmetric 1,6-conjugate addition of para-quinone methides (p-QMs), a class of challenging reactions with previous limited success. Benefiting from chiral Bronsted acid catalysis, which allows in situ formation of p-QMs, our reaction expands the scope to general p-QMs with various substitution patterns. It also enables efficient intermolecular formation of all-carbon quaternary stereocenters with high enantioselectivity.
