658689-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 658689-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,8,6,8 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 658689-59:
(8*6)+(7*5)+(6*8)+(5*6)+(4*8)+(3*9)+(2*5)+(1*9)=239
239 % 10 = 9
So 658689-59-9 is a valid CAS Registry Number.
