2646-27-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2646-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2646-27:
(6*2)+(5*6)+(4*4)+(3*6)+(2*2)+(1*7)=87
87 % 10 = 7
So 2646-27-7 is a valid CAS Registry Number.
