105211-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105211-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,2,1 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 105211-12:
(8*1)+(7*0)+(6*5)+(5*2)+(4*1)+(3*1)+(2*1)+(1*2)=59
59 % 10 = 9
So 105211-12-9 is a valid CAS Registry Number.
