192820-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 192820-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,8,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 192820-87:
(8*1)+(7*9)+(6*2)+(5*8)+(4*2)+(3*0)+(2*8)+(1*7)=154
154 % 10 = 4
