91670-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91670-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,7 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91670-52:
(7*9)+(6*1)+(5*6)+(4*7)+(3*0)+(2*5)+(1*2)=139
139 % 10 = 9
So 91670-52-9 is a valid CAS Registry Number.
