27593-18-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27593-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,5,9 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27593-18:
(7*2)+(6*7)+(5*5)+(4*9)+(3*3)+(2*1)+(1*8)=136
136 % 10 = 6
So 27593-18-6 is a valid CAS Registry Number.
