249620-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 249620-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,6,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 249620-64:
(8*2)+(7*4)+(6*9)+(5*6)+(4*2)+(3*0)+(2*6)+(1*4)=152
152 % 10 = 2
So 249620-64-2 is a valid CAS Registry Number.
