Check Digit Verification of cas no

The CAS Registry Mumber 73289-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,8 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73289-80:
(7*7)+(6*3)+(5*2)+(4*8)+(3*9)+(2*8)+(1*0)=152
152 % 10 = 2
So 73289-80-2 is a valid CAS Registry Number.

A highly efficient approach to vanillin starting from 4-cresol

Jiang, Jian-An,Chen, Cheng,Guo, Ying,Liao, Dao-Hua,Pan, Xian-Dao,Ji, Ya-Fei

supporting information, p. 2807 - 2814 (2014/05/06)

A highly efficient approach to the famous flavor and fragrance compound vanillin has been developed starting from 4-cresol with the attention focused on improving the sustainability of all the reactions. The approach involves a three-step sequence of the quasi-quantitative selective clean oxybromination of 4-cresol, the high-yield selective aerobic oxidation of 2-bromo-4-cresol, and the quantitative methoxylation of 3-bromo-4-hydroxybenzaldehyde with the recovery of pure methanol. Herein, the pivotal oxidation and methoxylation reactions are logically investigated and developed into two concise methodologies. As a green alternative, the approach holds significant value for the sustainable manufacturing of vanillin. the Partner Organisations 2014.
