81654-07-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81654-07-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,5 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81654-07:
(7*8)+(6*1)+(5*6)+(4*5)+(3*4)+(2*0)+(1*7)=131
131 % 10 = 1
So 81654-07-1 is a valid CAS Registry Number.
