905697-49-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 905697-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,6,9 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 905697-49:
(8*9)+(7*0)+(6*5)+(5*6)+(4*9)+(3*7)+(2*4)+(1*9)=206
206 % 10 = 6
So 905697-49-6 is a valid CAS Registry Number.
