91732-72-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91732-72-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,3 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91732-72:
(7*9)+(6*1)+(5*7)+(4*3)+(3*2)+(2*7)+(1*2)=138
138 % 10 = 8
So 91732-72-8 is a valid CAS Registry Number.
