135840-36-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135840-36-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,8,4 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135840-36:
(8*1)+(7*3)+(6*5)+(5*8)+(4*4)+(3*0)+(2*3)+(1*6)=127
127 % 10 = 7
So 135840-36-7 is a valid CAS Registry Number.

The cyclic carbamate (3), a key intermediate in our projected synthesis of trenudine (2), has been synthesised from 3,4-epoxycyclohexene (4) by ozonolytic cleavage of the cyclopentene (9) as a key step.
