103837-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103837-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,3 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103837-20:
(8*1)+(7*0)+(6*3)+(5*8)+(4*3)+(3*7)+(2*2)+(1*0)=103
103 % 10 = 3
So 103837-20-3 is a valid CAS Registry Number.
