83451-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83451-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,5 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83451-40:
(7*8)+(6*3)+(5*4)+(4*5)+(3*1)+(2*4)+(1*0)=125
125 % 10 = 5
So 83451-40-5 is a valid CAS Registry Number.
