188789-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188789-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,8 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188789-98:
(8*1)+(7*8)+(6*8)+(5*7)+(4*8)+(3*9)+(2*9)+(1*8)=232
232 % 10 = 2
So 188789-98-2 is a valid CAS Registry Number.
