107933-50-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107933-50-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,3 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107933-50:
(8*1)+(7*0)+(6*7)+(5*9)+(4*3)+(3*3)+(2*5)+(1*0)=126
126 % 10 = 6
So 107933-50-6 is a valid CAS Registry Number.
