691407-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 691407-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,4,0 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 691407-89:
(8*6)+(7*9)+(6*1)+(5*4)+(4*0)+(3*7)+(2*8)+(1*9)=183
183 % 10 = 3
So 691407-89-3 is a valid CAS Registry Number.
