69744-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69744-63-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,7,4 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69744-63:
(7*6)+(6*9)+(5*7)+(4*4)+(3*4)+(2*6)+(1*3)=174
174 % 10 = 4
So 69744-63-4 is a valid CAS Registry Number.
