103954-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103954-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 103954-34:
(8*1)+(7*0)+(6*3)+(5*9)+(4*5)+(3*4)+(2*3)+(1*4)=113
113 % 10 = 3
So 103954-34-3 is a valid CAS Registry Number.
