Check Digit Verification of cas no
The CAS Registry Mumber 33422-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,2 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33422-32:
(7*3)+(6*3)+(5*4)+(4*2)+(3*2)+(2*3)+(1*2)=81
81 % 10 = 1
So 33422-32-1 is a valid CAS Registry Number.

Site and stereoselectivity of the cyclopropanation of unsymmetrically substituted 1,3-dienes by the Simmons-Smith reaction
Guerreiro, Mario Cesar,Schuchardt, Ulf
, p. 1793 - 1800 (2007/10/03)
In the Simmons-Smith reaction, 1,3-dienes are preferentially cyclopropanated at the more electron-rich double bond to afford the trans-vinylcyclopropane; an allylic hydroxyl group increases the reactivity and directs the cyclopropanation to the adjacent double bond.
