Check Digit Verification of cas no
The CAS Registry Mumber 189949-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,9,4 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189949-08:
(8*1)+(7*8)+(6*9)+(5*9)+(4*4)+(3*9)+(2*0)+(1*8)=214
214 % 10 = 4
So 189949-08-4 is a valid CAS Registry Number.
