Check Digit Verification of cas no

The CAS Registry Mumber 63975-76-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,9,7 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63975-76:
(7*6)+(6*3)+(5*9)+(4*7)+(3*5)+(2*7)+(1*6)=168
168 % 10 = 8
So 63975-76-8 is a valid CAS Registry Number.

A Revised Modular Approach to (–)-trans-Δ8-THC and Derivatives Through Late-Stage Suzuki–Miyaura Cross-Coupling Reactions

Bloemendal, Victor R. L. J.,Sondag, Daan,Elferink, Hidde,Boltje, Thomas J.,van Hest, Jan. C. M.,Rutjes, Floris P. J. T.

, p. 2289 - 2296 (2019/04/03)

A revised modular approach to various synthetic (–)-trans-Δ8-THC derivatives through late-stage Suzuki–Miyaura cross-coupling reactions is disclosed. Ten derivatives were synthesized allowing both sp2- and sp3-hybridized cross-coupling partners with minimal β-hydride elimination. Importantly, we demonstrate that a para-bromo-substituted THC scaffold for Suzuki–Miyaura cross-coupling reactions has been initially reported incorrectly in recent literature.
