83291-66-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83291-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,9 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83291-66:
(7*8)+(6*3)+(5*2)+(4*9)+(3*1)+(2*6)+(1*6)=141
141 % 10 = 1
So 83291-66-1 is a valid CAS Registry Number.
