Check Digit Verification of cas no
The CAS Registry Mumber 5832-44-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,3 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5832-44:
(6*5)+(5*8)+(4*3)+(3*2)+(2*4)+(1*4)=100
100 % 10 = 0
So 5832-44-0 is a valid CAS Registry Number.

Selective ortho methylation of nitroheteroaryls by vicarious nucleophilic substitution

(Chemical Equation Presented) An efficient and scalable three-step one-pot approach to 6-methyl-5-nitroisoquinoline (1) from inexpensive 5-nitroisoquinoline, utilizing the vicarious nucleophilic substitution (VNS) as a key step, is described. The optimized reaction conditions can be applied to a limited number of other aromatic and heteroaromatic nitro compounds. Attempts to understand the observed selectivity in the VNS step led to the discovery of two new reaction pathways under VNS conditions, one leading to an isoxazole and the other resulting in the formal cyclopropanation of an aromatic nitro compound.
