Check Digit Verification of cas no

The CAS Registry Mumber 1567388-65-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,7,3,8 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1567388-65:
(9*1)+(8*5)+(7*6)+(6*7)+(5*3)+(4*8)+(3*8)+(2*6)+(1*5)=221
221 % 10 = 1
So 1567388-65-1 is a valid CAS Registry Number.

Efficient Co(OAc)2-catalyzed aerobic oxidation of EWG-substituted 4-cresols to access 4-hydroxybenzaldehydes

Jiang, Jian-An,Du, Jia-Lei,Liao, Dao-Hua,Wang, Zhan-Guo,Ji, Ya-Fei

supporting information, p. 1406 - 1411 (2014/03/21)

We reported an efficient ligand-free Co(OAc)2·4H 2O/NaOH/O2/ethylene glycol reaction system that enables selective aerobic oxidation of a wide range of substrates covering 2,6-di-EWG-, 2,3,6-tri-EWG-, 2-EWG-, and 2-EWG-6-EDG-substituted 4-cresols into the corresponding 4-hydroxybenzaldehydes. Based on the experimental investigations and well-defined p-benzoquinone methides, a plausible reaction mechanism was proposed. Considering the simplicity of the procedure and importance of the products, the methodology was expected to become a favorable and practical tool in related benzylic C(sp3)-H functionalization chemistry.
