105020-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105020-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,2 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 105020-23:
(8*1)+(7*0)+(6*5)+(5*0)+(4*2)+(3*0)+(2*2)+(1*3)=53
53 % 10 = 3
So 105020-23-3 is a valid CAS Registry Number.
