61744-62-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61744-62-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,7,4 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61744-62:
(7*6)+(6*1)+(5*7)+(4*4)+(3*4)+(2*6)+(1*2)=125
125 % 10 = 5
So 61744-62-5 is a valid CAS Registry Number.
