103476-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103476-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,7 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103476-49:
(8*1)+(7*0)+(6*3)+(5*4)+(4*7)+(3*6)+(2*4)+(1*9)=109
109 % 10 = 9
So 103476-49-9 is a valid CAS Registry Number.
