Check Digit Verification of cas no

The CAS Registry Mumber 1257313-60-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,1 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257313-60:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*1)+(3*3)+(2*6)+(1*0)=142
142 % 10 = 2
So 1257313-60-2 is a valid CAS Registry Number.

Scaling out by microwave-assisted, continuous flow organic synthesis (MACOS): Multi-gram synthesis of bromo- and fluoro-benzofused Sultams Benzthiaoxazepine-1,1-dioxides

(Figure Presented). Go with the flow! Using a combination of continuous-flow techniques and microwave irradiation, a 19-member collection of 5-10 gram quantities of benzthiaoxazepine-1,1-dioxides has been produced (see scheme). The elimination of intermediate- and largescale process optimization by invoking the concept of scale-out (rather than scale up) has significantly reduced the time necessary to prepare these compounds.
