118744-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118744-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,4 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118744-05:
(8*1)+(7*1)+(6*8)+(5*7)+(4*4)+(3*4)+(2*0)+(1*5)=131
131 % 10 = 1
So 118744-05-1 is a valid CAS Registry Number.
