Check Digit Verification of cas no

The CAS Registry Mumber 836643-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,6,6,4 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 836643-54:
(8*8)+(7*3)+(6*6)+(5*6)+(4*4)+(3*3)+(2*5)+(1*4)=190
190 % 10 = 0
So 836643-54-0 is a valid CAS Registry Number.

New reagent system for attaining high regio- and stereoselectivities in allylic displacement of 4-cyclopentene-1,3-diol monoacetate with aryl- and alkenylmagnesium bromides

Kobayashi, Yuichi,Nakata, Kenya,Ainai, Takayuki

, p. 183 - 186 (2007/10/03)

(Chemical Equation Presented) Low regioselectivity of RMgBr (R = aryl, alkenyl) in the CuCN-catalyzed reaction with 4-cyclopentene-1,3-diol monoacetate is improved by addition of LiCl or MgCl2 to a similar extent as previously obtained with RMg
