Check Digit Verification of cas no
The CAS Registry Mumber 1058744-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,8,7,4 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1058744-83:
(9*1)+(8*0)+(7*5)+(6*8)+(5*7)+(4*4)+(3*4)+(2*8)+(1*3)=174
174 % 10 = 4
So 1058744-83-4 is a valid CAS Registry Number.
