121682-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121682-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,8 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121682-91:
(8*1)+(7*2)+(6*1)+(5*6)+(4*8)+(3*2)+(2*9)+(1*1)=115
115 % 10 = 5
So 121682-91-5 is a valid CAS Registry Number.

Schmidt, Richard R.,Frick, Wendelin
, p. 7163 - 7170 (2007/10/02)
The aryllithium species 5a-A and 5b-A generated via bromine/lithium exchange reaction, afforded with the per-O-benzylated D-glucose 6 the adducts 9a,b; subsequent oxidation furnished the corresponding ketones 10a,b.Compound 10a was also obtained from 5a-A
