Check Digit Verification of cas no
The CAS Registry Mumber 420-90-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 420-90:
(5*4)+(4*2)+(3*0)+(2*9)+(1*0)=46
46 % 10 = 6
So 420-90-6 is a valid CAS Registry Number.

gem-(Difluoroallyl)lithium may be generated by lithium-bromine exchange between n-butyllithium and CH//2 equals CHCF//2Br at minus 95 degree C by using an in situ procedure. When this preparation is carried out in the presence of chlorosilanes, aldehydes, ketones, and esters, products are formed, often in good yield. The factors determining the regioselectivity in addition to C equals O of unsymmetrically substituted allylic lithium reagents are discussed.
