74282-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74282-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,8 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74282-52:
(7*7)+(6*4)+(5*2)+(4*8)+(3*2)+(2*5)+(1*2)=133
133 % 10 = 3
So 74282-52-3 is a valid CAS Registry Number.

Chelation-Controlled Synthesis of (+/-)-Muscarine
Still, W.Clark,Schneider, Josef A.
, p. 3375 - 3376 (1980)
The chelation controlled addition of Grignard reagents to chiral α-alkoxy aldehydes to give threo diol derivatives is synthetically useful in highly oxygenated systems and is used here as the key step in a novel synthesis of (+/-)-muscarine from cyclopentadiene.
