Check Digit Verification of cas no
The CAS Registry Mumber 188119-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,1 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 188119-06:
(8*1)+(7*8)+(6*8)+(5*1)+(4*1)+(3*9)+(2*0)+(1*6)=154
154 % 10 = 4
So 188119-06-4 is a valid CAS Registry Number.
