613675-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 613675-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,3,6,7 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 613675-91:
(8*6)+(7*1)+(6*3)+(5*6)+(4*7)+(3*5)+(2*9)+(1*1)=165
165 % 10 = 5
So 613675-91-5 is a valid CAS Registry Number.
