Check Digit Verification of cas no

The CAS Registry Mumber 688309-06-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,3,0 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 688309-06:
(8*6)+(7*8)+(6*8)+(5*3)+(4*0)+(3*9)+(2*0)+(1*6)=200
200 % 10 = 0
So 688309-06-0 is a valid CAS Registry Number.

Temperature-controlled synthesis of N-acyl anthranilamides and quinazoline-4ones via Pd-catalysed cascade consisting of isocyanide insertion

Khan, Irfan,Singh, Jaybir,Khan, Imran,Dutt, Sunil,Khan, Shahnawaz,Tyagi, Vikas

, p. 279 - 291 (2019)

A one step synthesis of functionlized N-acyl anthranilamide via Pd-catalyzed carboxamidation of o-halo substituted N-phenylamide consisting of isocyanide insertion followed by oxidation of the imine intermediate has been achived successfully. Furthermore,

Potassium hydroxide-promoted transition-metal-free synthesis of 4(3H)-quinazolinones

Qiu, Dezhi,Wang, Yanyan,Lu, Dongming,Zhou, Lihong,Zeng, Qingle

, p. 1343 - 1347 (2015/08/18)

We have developed a KOH-promoted transition-metal-free synthesis of 2-substituted 4(3H)-quinazolinones from anthranilamides and benzyl alcohols or cinnamyl alcohol with air as oxidant. The protocol is simple, practical, and cost saving. Graphical abstract: [Figure not available: see fulltext.]
