41744-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41744-30-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,7,4 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41744-30:
(7*4)+(6*1)+(5*7)+(4*4)+(3*4)+(2*3)+(1*0)=103
103 % 10 = 3
So 41744-30-3 is a valid CAS Registry Number.
