94855-20-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94855-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,5 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94855-20:
(7*9)+(6*4)+(5*8)+(4*5)+(3*5)+(2*2)+(1*0)=166
166 % 10 = 6
So 94855-20-6 is a valid CAS Registry Number.

EXTENDED SCOPE OF THE GRIGNARD REACTION OF β-HALOACETALS. USE OF ACYCLIC ACETALS
Greiner, A.
, p. 3547 - 3550 (2007/10/02)
Careful control of reaction conditions permits the high yield preparation of Grignard reagents fron β-halogenoacetals and their condensation with carbonyl compounds, regardless of the halogen (bromine, chlorine) or acetal structure (cyclic, acyclic).
