657396-77-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 657396-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,7,3,9 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 657396-77:
(8*6)+(7*5)+(6*7)+(5*3)+(4*9)+(3*6)+(2*7)+(1*7)=215
215 % 10 = 5
So 657396-77-5 is a valid CAS Registry Number.
