688739-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 688739-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,7,3 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 688739-24:
(8*6)+(7*8)+(6*8)+(5*7)+(4*3)+(3*9)+(2*2)+(1*4)=234
234 % 10 = 4
So 688739-24-4 is a valid CAS Registry Number.
