Check Digit Verification of cas no

The CAS Registry Mumber 643746-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,4 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 643746-52:
(8*6)+(7*4)+(6*3)+(5*7)+(4*4)+(3*6)+(2*5)+(1*2)=175
175 % 10 = 5
So 643746-52-5 is a valid CAS Registry Number.

An Expeditious Synthesis of (±)-Mimosifoliol Utilizing a Cascade Involving an o-Quinone Methide Intermediate

Tuttle, Kristin,Rodriguez, Andrew A.,Pettus, Thomas R. R.

, p. 2234 - 2236 (2003)

An efficient synthesis of (±)-mimosifoliol is reported. The key transformation involves a domino sequence leading to an o-quinone methide and its subsequent consumption in 1,4-conjugate addition with a vinyl Grignard reagent.
