30953-86-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 30953-86-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,9,5 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 30953-86:
(7*3)+(6*0)+(5*9)+(4*5)+(3*3)+(2*8)+(1*6)=117
117 % 10 = 7
So 30953-86-7 is a valid CAS Registry Number.
