76490-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76490-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,9 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76490-22:
(7*7)+(6*6)+(5*4)+(4*9)+(3*0)+(2*2)+(1*2)=147
147 % 10 = 7
So 76490-22-7 is a valid CAS Registry Number.

An efficient method for selective amino acid protection with proper differentiation between the two amino acid groups in meso-2,2'-diaminopimelic acid has been achieved (7 -> 8 -> 9 -> 10 -> 11) and applied to the synthesis of FK-156 (10 -> 12 -> 14 -> 1)
