690255-85-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 690255-85-7 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 690255-85:
(8*6)+(7*9)+(6*0)+(5*2)+(4*5)+(3*5)+(2*8)+(1*5)=177
177 % 10 = 7
So 690255-85-7 is a valid CAS Registry Number.
