71861-60-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71861-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,6 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71861-60:
(7*7)+(6*1)+(5*8)+(4*6)+(3*1)+(2*6)+(1*0)=134
134 % 10 = 4
So 71861-60-4 is a valid CAS Registry Number.

When the enzyme deaminase acts alone on porphobilinogen, it releases a tarnsient intermediate into the medium which is unaffected by further treatment with a large excess of deaminase.The intermediate undergoes rapid ring-closure chemically (t1/2/su
