191661-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191661-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,6,6 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 191661-01:
(8*1)+(7*9)+(6*1)+(5*6)+(4*6)+(3*1)+(2*0)+(1*1)=135
135 % 10 = 5
So 191661-01-5 is a valid CAS Registry Number.
