Check Digit Verification of cas no
The CAS Registry Mumber 87044-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,4 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87044-57:
(7*8)+(6*7)+(5*0)+(4*4)+(3*4)+(2*5)+(1*7)=143
143 % 10 = 3
So 87044-57-3 is a valid CAS Registry Number.
