720681-07-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 720681-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,0,6,8 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 720681-07:
(8*7)+(7*2)+(6*0)+(5*6)+(4*8)+(3*1)+(2*0)+(1*7)=142
142 % 10 = 2
So 720681-07-2 is a valid CAS Registry Number.
