161693-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161693-86-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,6,9 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 161693-86:
(8*1)+(7*6)+(6*1)+(5*6)+(4*9)+(3*3)+(2*8)+(1*6)=153
153 % 10 = 3
So 161693-86-3 is a valid CAS Registry Number.

First unequivocal synthesis of 1 or 8-N-monosubstituted 1,4,8,12-tetraazacyclopentadecane

, p. 1197 - 1208 (2007/10/02)
A novel method derived from Kaden's modification of the Richman and Atkins's cyclization using tosylated synthons allows the unequivocal synthesis of 1 and 8-monofunctionalized 1,4,8,12-tetraazacyclo-pentadecane. Both syntheses are described.
