Check Digit Verification of cas no

The CAS Registry Mumber 101901-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,9,0 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 101901-51:
(8*1)+(7*0)+(6*1)+(5*9)+(4*0)+(3*1)+(2*5)+(1*1)=73
73 % 10 = 3
So 101901-51-3 is a valid CAS Registry Number.

Selective Phthalimido-N-oxyl (PINO)-Catalyzed C-H Cyanation of Adamantane Derivatives

Berndt, Jan-Philipp,Erb, Frederik R.,Ochmann, Lukas,Beppler, Jaqueline,Schreiner, Peter R.

, p. 493 - 498 (2019)

We present a new method for the selective C(sp 3)-H cyanation of adamantane derivatives with PINO as the hydrogen abstracting reagent. A cyano radical is thereby transferred from p - toluenesulfonyl cyanide, allowing the cyanation of adamantane derivatives in up to 71% yield. The protocol presents a novel way to orthogonally functionalized adamantanes that are otherwise difficult to prepare. Mechanistic studies support the hypothesis of a radical pathway.
