3972-95-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3972-95-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,7 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3972-95:
(6*3)+(5*9)+(4*7)+(3*2)+(2*9)+(1*5)=120
120 % 10 = 0
So 3972-95-0 is a valid CAS Registry Number.
