Check Digit Verification of cas no
The CAS Registry Mumber 85872-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,7 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85872-56:
(7*8)+(6*5)+(5*8)+(4*7)+(3*2)+(2*5)+(1*6)=176
176 % 10 = 6
So 85872-56-6 is a valid CAS Registry Number.
