81830-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81830-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,3 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81830-45:
(7*8)+(6*1)+(5*8)+(4*3)+(3*0)+(2*4)+(1*5)=127
127 % 10 = 7
So 81830-45-7 is a valid CAS Registry Number.
