83646-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83646-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,4 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83646-31:
(7*8)+(6*3)+(5*6)+(4*4)+(3*6)+(2*3)+(1*1)=145
145 % 10 = 5
So 83646-31-5 is a valid CAS Registry Number.
