Check Digit Verification of cas no

The CAS Registry Mumber 337921-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,9,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 337921-66:
(8*3)+(7*3)+(6*7)+(5*9)+(4*2)+(3*1)+(2*6)+(1*6)=161
161 % 10 = 1
So 337921-66-1 is a valid CAS Registry Number.

Asymmetric Hydroarylation of Enones via Nickel-Catalyzed 5- Endo-Trig Cyclization

Qin, Xurong,Yao Lee, Marcus Wen,Zhou, Jianrong Steve

supporting information, p. 5990 - 5994 (2019/08/20)

A nickel-catalyzed reductive cyclization of enones affords a wide array of indanones in high enantiomeric induction. The reaction is featured with an unprecedented broad scope of substrates. The versatility of the new method is demonstrated in several short stereoselective syntheses of medically valuable (R)-tolterodine, parent and deuterated (+)-indatraline, and an antitumor natural product, (+)-multisianthol. In comparison, these compounds cannot be prepared satisfactorily via analogous processes catalyzed by palladium.
