20978-95-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20978-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,7 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20978-95:
(7*2)+(6*0)+(5*9)+(4*7)+(3*8)+(2*9)+(1*5)=134
134 % 10 = 4
So 20978-95-4 is a valid CAS Registry Number.
