Check Digit Verification of cas no
The CAS Registry Mumber 849186-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,1,8 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 849186-15:
(8*8)+(7*4)+(6*9)+(5*1)+(4*8)+(3*6)+(2*1)+(1*5)=208
208 % 10 = 8
So 849186-15-8 is a valid CAS Registry Number.
