146306-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146306-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,3,0 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 146306-54:
(8*1)+(7*4)+(6*6)+(5*3)+(4*0)+(3*6)+(2*5)+(1*4)=119
119 % 10 = 9
So 146306-54-9 is a valid CAS Registry Number.

Biotin biosynthesis: synthesis of the postulated intermediate
Mingotaud, A. F.,Florentin, D.,Marquet, A.
, p. 457 - 462 (2007/10/02)
Several attempts to build an imidazolidinone ring from an allylic alcohol are presented.The final sequence implies the construction of a diazide, via an epoxide, and cyclization of the corresponding diamine with triphosgene. Key words: Biotin biosynthesis
