105891-64-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105891-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,8,9 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 105891-64:
(8*1)+(7*0)+(6*5)+(5*8)+(4*9)+(3*1)+(2*6)+(1*4)=133
133 % 10 = 3
So 105891-64-3 is a valid CAS Registry Number.
