105897-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105897-81-2 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 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105897-81:
(8*1)+(7*0)+(6*5)+(5*8)+(4*9)+(3*7)+(2*8)+(1*1)=152
152 % 10 = 2
So 105897-81-2 is a valid CAS Registry Number.
