143836-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143836-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,3 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143836-20:
(8*1)+(7*4)+(6*3)+(5*8)+(4*3)+(3*6)+(2*2)+(1*0)=128
128 % 10 = 8
So 143836-20-8 is a valid CAS Registry Number.

Diastereoselective formation of pyruvylated glycosides from partly protected sugars and methyl pyruvate
Ziegler,Eckhardt,Herold
, p. 4413 - 4416 (1992)
Various partly protected sugars (gluco-, manno-, and galactopyranosides) were acetalized with methyl pyruvate in moderate to good yield with BF3-etherate as the condensing reagent. Thus, (1-methoxycarbonyl)ethylidene glycosides were obtained di
