Check Digit Verification of cas no
The CAS Registry Mumber 35980-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,9,8 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 35980-63:
(7*3)+(6*5)+(5*9)+(4*8)+(3*0)+(2*6)+(1*3)=143
143 % 10 = 3
So 35980-63-3 is a valid CAS Registry Number.

First unequivocal synthesis of 1 or 8-N-monosubstituted 1,4,8,12-tetraazacyclopentadecane
Granier, Colin,Guilard, Roger
, 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.
