65031-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65031-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,3 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65031-34:
(7*6)+(6*5)+(5*0)+(4*3)+(3*1)+(2*3)+(1*4)=97
97 % 10 = 7
So 65031-34-7 is a valid CAS Registry Number.
