Check Digit Verification of cas no

The CAS Registry Mumber 85972-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,7 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85972-99:
(7*8)+(6*5)+(5*9)+(4*7)+(3*2)+(2*9)+(1*9)=192
192 % 10 = 2
So 85972-99-2 is a valid CAS Registry Number.

STERICALLY CROWDED CYCLOPROPANATION CATALYSTS. SYN-SELECTIVITY USING RHODIUM(III)PORPHYRINS

Callot, H. J.,Metz, F.,Piechocki, C.

, p. 2365 - 2369 (1982)

Rhodium(III)porphyrins catalyze the decomposition of ethyl diazoacetate and the transfer of ethoxycarbonylcarbene to alkenes to form cyclopropanes in moderate to high yields.When compared with other catalysts a large syn-selectivity was observed on reaction with cis-alkenes.This selectivity increased with the size of the substituents, and suggested a preferencial direction of approach of the alkene towards a rhodium-carbene complex.
