690255-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 690255-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,2,5 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 690255-83:
(8*6)+(7*9)+(6*0)+(5*2)+(4*5)+(3*5)+(2*8)+(1*3)=175
175 % 10 = 5
So 690255-83-5 is a valid CAS Registry Number.
