100973-72-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100973-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 100973-72:
(8*1)+(7*0)+(6*0)+(5*9)+(4*7)+(3*3)+(2*7)+(1*2)=106
106 % 10 = 6
So 100973-72-6 is a valid CAS Registry Number.
