Check Digit Verification of cas no
The CAS Registry Mumber 158523-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,2 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 158523-34:
(8*1)+(7*5)+(6*8)+(5*5)+(4*2)+(3*3)+(2*3)+(1*4)=143
143 % 10 = 3
So 158523-34-3 is a valid CAS Registry Number.
