689252-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 689252-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,9,2,5 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 689252-61:
(8*6)+(7*8)+(6*9)+(5*2)+(4*5)+(3*2)+(2*6)+(1*1)=207
207 % 10 = 7
So 689252-61-7 is a valid CAS Registry Number.
