1330744-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1330744-81-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,0,7,4 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1330744-81:
(9*1)+(8*3)+(7*3)+(6*0)+(5*7)+(4*4)+(3*4)+(2*8)+(1*1)=134
134 % 10 = 4
So 1330744-81-4 is a valid CAS Registry Number.
