917766-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917766-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,7,6 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917766-70:
(8*9)+(7*1)+(6*7)+(5*7)+(4*6)+(3*6)+(2*7)+(1*0)=212
212 % 10 = 2
So 917766-70-2 is a valid CAS Registry Number.

, p. 5605 - 5608 (2007/10/03)
The synthesis of (±)-symbioimine (1) has been completed in only 12 linear steps in 8% overall yield. The key step is the treatment of 13b with BF3·Et2O to generate N-carboalkoxydihydropyridinium cation 14b, which undergoes a novel stereospecific intramole
