91383-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91383-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,8 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91383-46:
(7*9)+(6*1)+(5*3)+(4*8)+(3*3)+(2*4)+(1*6)=139
139 % 10 = 9
So 91383-46-9 is a valid CAS Registry Number.
