Check Digit Verification of cas no
The CAS Registry Mumber 1255666-86-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,6,6 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1255666-86:
(9*1)+(8*2)+(7*5)+(6*5)+(5*6)+(4*6)+(3*6)+(2*8)+(1*6)=184
184 % 10 = 4
So 1255666-86-4 is a valid CAS Registry Number.
