Check Digit Verification of cas no
The CAS Registry Mumber 866251-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,6,2,5 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 866251-28:
(8*8)+(7*6)+(6*6)+(5*2)+(4*5)+(3*1)+(2*2)+(1*8)=187
187 % 10 = 7
So 866251-28-7 is a valid CAS Registry Number.
