91870-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91870-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,7 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91870-94:
(7*9)+(6*1)+(5*8)+(4*7)+(3*0)+(2*9)+(1*4)=159
159 % 10 = 9
So 91870-94-9 is a valid CAS Registry Number.
