57136-16-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57136-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,3 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57136-16:
(7*5)+(6*7)+(5*1)+(4*3)+(3*6)+(2*1)+(1*6)=120
120 % 10 = 0
So 57136-16-0 is a valid CAS Registry Number.
