Check Digit Verification of cas no
The CAS Registry Mumber 56660-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,6,6 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 56660-19:
(7*5)+(6*6)+(5*6)+(4*6)+(3*0)+(2*1)+(1*9)=136
136 % 10 = 6
So 56660-19-6 is a valid CAS Registry Number.
