Check Digit Verification of cas no
The CAS Registry Mumber 75980-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,8 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75980-60:
(7*7)+(6*5)+(5*9)+(4*8)+(3*0)+(2*6)+(1*0)=168
168 % 10 = 8
So 75980-60-8 is a valid CAS Registry Number.

, (2021/01/14)
A novel palladium-catalyzed decarbonylation of aroyl phosphine oxides to prepare phosphine oxides from carboxylic acids is developed. Without the adjacent “anchoring atom”, the challenging C–P bond activation is achieved in high selectivity. The disclosure of this reaction provides a new example of C–P bond activation and helps to extend the understanding of the property of C–P bond.
