Check Digit Verification of cas no
The CAS Registry Mumber 875664-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,6,6 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 875664-44:
(8*8)+(7*7)+(6*5)+(5*6)+(4*6)+(3*4)+(2*4)+(1*4)=221
221 % 10 = 1
So 875664-44-1 is a valid CAS Registry Number.
