1334809-55-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1334809-55-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,8,0 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1334809-55:
(9*1)+(8*3)+(7*3)+(6*4)+(5*8)+(4*0)+(3*9)+(2*5)+(1*5)=160
160 % 10 = 0
So 1334809-55-0 is a valid CAS Registry Number.

A smooth transition from (R)-carvone to a β-lactone and then to (+)-omphadiol characterizes the first total synthesis of this sesquiterpene, which was achieved in ten steps and 18 overall yield. All six contiguous stereogenic centers were introduced in a
