697765-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 697765-19-8 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, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 697765-19:
(8*6)+(7*9)+(6*7)+(5*7)+(4*6)+(3*5)+(2*1)+(1*9)=238
238 % 10 = 8
So 697765-19-8 is a valid CAS Registry Number.
