81380-07-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81380-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,8 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81380-07:
(7*8)+(6*1)+(5*3)+(4*8)+(3*0)+(2*0)+(1*7)=116
116 % 10 = 6
So 81380-07-6 is a valid CAS Registry Number.
