65654-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65654-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,5 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.Calculate Digit Verification of CAS Registry Number 65654-61:
(7*6)+(6*5)+(5*6)+(4*5)+(3*4)+(2*6)+(1*1)=147
147 % 10 = 7
So 65654-61-7 is a valid CAS Registry Number.
