Check Digit Verification of cas no
The CAS Registry Mumber 842167-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,2,1,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 842167-67:
(8*8)+(7*4)+(6*2)+(5*1)+(4*6)+(3*7)+(2*6)+(1*7)=173
173 % 10 = 3
So 842167-67-3 is a valid CAS Registry Number.

A practical and efficient method is established for the direct oxidative lactonization of the C(sp3)-H bonds relying on visible-light-induced photoredox catalysis. This protocol expediently allows the delivery of diverse phthalides using oxygen as the sole terminal oxidant under metal-free conditions at room temperature. Notably, the choice of an appropriate hydrogen atom transfer (HAT) cocatalyst is revealed to be critical for the success of this process.
