909707-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909707-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,7,0 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 909707-71:
(8*9)+(7*0)+(6*9)+(5*7)+(4*0)+(3*7)+(2*7)+(1*1)=197
197 % 10 = 7
So 909707-71-7 is a valid CAS Registry Number.
