105638-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105638-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,6,3 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105638-41:
(8*1)+(7*0)+(6*5)+(5*6)+(4*3)+(3*8)+(2*4)+(1*1)=113
113 % 10 = 3
So 105638-41-3 is a valid CAS Registry Number.
