Check Digit Verification of cas no
The CAS Registry Mumber 187263-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,2,6 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 187263-86:
(8*1)+(7*8)+(6*7)+(5*2)+(4*6)+(3*3)+(2*8)+(1*6)=171
171 % 10 = 1
So 187263-86-1 is a valid CAS Registry Number.
