928613-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928613-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,6,1 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 928613-92:
(8*9)+(7*2)+(6*8)+(5*6)+(4*1)+(3*3)+(2*9)+(1*2)=197
197 % 10 = 7
So 928613-92-7 is a valid CAS Registry Number.
