697765-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 697765-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,7,7,6 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 697765-23:
(8*6)+(7*9)+(6*7)+(5*7)+(4*6)+(3*5)+(2*2)+(1*3)=234
234 % 10 = 4
So 697765-23-4 is a valid CAS Registry Number.
