92220-10-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92220-10-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,2,2 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 92220-10:
(7*9)+(6*2)+(5*2)+(4*2)+(3*0)+(2*1)+(1*0)=95
95 % 10 = 5
So 92220-10-5 is a valid CAS Registry Number.

Roush, William R.,Blizzard, Timothy A.
, p. 4332 - 4339 (2007/10/02)
A four-step synthesis of verrucarin B (3) from verrucarol (2) is described.Coupling of 2 with in situ generated carboxylic acid 5 proceeded with moderate regioselectivity and afforded trichothecene monoester 14 in only 35 percent yield.It was necessary th
