1197212-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1197212-87-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,2,1 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1197212-87:
(9*1)+(8*1)+(7*9)+(6*7)+(5*2)+(4*1)+(3*2)+(2*8)+(1*7)=165
165 % 10 = 5
So 1197212-87-5 is a valid CAS Registry Number.
