Check Digit Verification of cas no

The CAS Registry Mumber 99678-01-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,7 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99678-01:
(7*9)+(6*9)+(5*6)+(4*7)+(3*8)+(2*0)+(1*1)=200
200 % 10 = 0
So 99678-01-0 is a valid CAS Registry Number.

A metal-free method for the facile synthesis of indanonesviathe intramolecular hydroacylation of 2-vinylbenzaldehyde

He, Guoxue,Ma, Jinyu,Zhou, Jianhui,Li, Chunpu,Liu, Hong,Zhou, Yu

supporting information, p. 1036 - 1040 (2021/02/09)

A facile method for the synthesis of indanones was developed under metal- and additive-free conditions, whereinl-proline served as an efficient and environmentally benign catalyst. Compared with previously synthesized indanones, synthesis by the transition-metal-catalyzed intramolecular hydroacylation of 2-vinylbenzaldehyde provided a more green synthetic pathway to indanone scaffolds with good to excellent yields. More importantly, it could be used to synthsize the anti-AD drug donepezil.
