84072-07-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84072-07-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,7 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84072-07:
(7*8)+(6*4)+(5*0)+(4*7)+(3*2)+(2*0)+(1*7)=121
121 % 10 = 1
So 84072-07-1 is a valid CAS Registry Number.
