105283-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105283-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,2,8 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 105283-39:
(8*1)+(7*0)+(6*5)+(5*2)+(4*8)+(3*3)+(2*3)+(1*9)=104
104 % 10 = 4
So 105283-39-4 is a valid CAS Registry Number.
