Check Digit Verification of cas no
The CAS Registry Mumber 55556-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,5 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 55556-85:
(7*5)+(6*5)+(5*5)+(4*5)+(3*6)+(2*8)+(1*5)=149
149 % 10 = 9
So 55556-85-9 is a valid CAS Registry Number.

THE OXIDATION OF HYDROXYLAMINE BY FREMY'S SALT. PREPARATION OF N-NITROSAMINES AND TETRAZENES
Tato, M. P. Vazquez,Castedo, Luis,Riguera, Ricardo
, p. 623 - 626 (2007/10/02)
Treatment of secondary amines with Fremy's salt in aqueous sodium carbonate solution and in the presence of hydroxylamine gives a high yield of either N-nitrosamines or sym-tetrazenes.A mechanism for these conversions is proposed.
