109958-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109958-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,5 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109958-70:
(8*1)+(7*0)+(6*9)+(5*9)+(4*5)+(3*8)+(2*7)+(1*0)=165
165 % 10 = 5
So 109958-70-5 is a valid CAS Registry Number.

, p. 279 - 282 (1982)
DL-Validoxylamine B was first synthesized by the reaction of DL-4,7:5,6-di-O-isopropylidene-(1,4,6/5)-4,5,6-trihydroxy-3-hydroxy-methyl-2-cyclohexenylamine with DL-3,4-di-O-acetyl-1,2-anhydro-5,7-O-benzylidene-(1,2,4,6/3,5)-6-hydroxymethyl-1,2,3,4,5-cyclo
