78920-92-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78920-92-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,2 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78920-92:
(7*7)+(6*8)+(5*9)+(4*2)+(3*0)+(2*9)+(1*2)=170
170 % 10 = 0
So 78920-92-0 is a valid CAS Registry Number.
