1400744-49-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1400744-49-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,7,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1400744-49:
(9*1)+(8*4)+(7*0)+(6*0)+(5*7)+(4*4)+(3*4)+(2*4)+(1*9)=121
121 % 10 = 1
So 1400744-49-1 is a valid CAS Registry Number.
