Check Digit Verification of cas no
The CAS Registry Mumber 261-27-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 261-27:
(5*2)+(4*6)+(3*1)+(2*2)+(1*7)=48
48 % 10 = 8
So 261-27-8 is a valid CAS Registry Number.
