Check Digit Verification of cas no

The CAS Registry Mumber 890653-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,6,5 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 890653-19:
(8*8)+(7*9)+(6*0)+(5*6)+(4*5)+(3*3)+(2*1)+(1*9)=197
197 % 10 = 7
So 890653-19-7 is a valid CAS Registry Number.

Hydroxylamine as an ammonia equivalent in microwave-enhanced aminocarbonylations

Wu, Xiongyu,Wannberg, Johan,Larhed, Mats

, p. 4665 - 4670 (2006)

A novel palladium-catalyzed and Mo(CO)6 promoted aminocarbonylation protocol was developed for rapid generation of primary aromatic amides from aryl bromides and iodides. Employing controlled microwave heating, hydroxylamine was first reduced in situ to ammonia, which thereafter reacted with carbon monoxide and the aryl halide substrate, delivering the benzamide product in less than 20 min. Based on this in situ carbonylation, a facile preparation of a novel HIV-1 protease inhibitor was achieved.
