Check Digit Verification of cas no
The CAS Registry Mumber 112849-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,4 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112849-17:
(8*1)+(7*1)+(6*2)+(5*8)+(4*4)+(3*9)+(2*1)+(1*7)=119
119 % 10 = 9
So 112849-17-9 is a valid CAS Registry Number.
