67565-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67565-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,6 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67565-41:
(7*6)+(6*7)+(5*5)+(4*6)+(3*5)+(2*4)+(1*1)=157
157 % 10 = 7
So 67565-41-7 is a valid CAS Registry Number.
