156696-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156696-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,9 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156696-19:
(8*1)+(7*5)+(6*6)+(5*6)+(4*9)+(3*6)+(2*1)+(1*9)=174
174 % 10 = 4
So 156696-19-4 is a valid CAS Registry Number.
