103744-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103744-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,4 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103744-20:
(8*1)+(7*0)+(6*3)+(5*7)+(4*4)+(3*4)+(2*2)+(1*0)=93
93 % 10 = 3
So 103744-20-3 is a valid CAS Registry Number.
