1219811-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1219811-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,8,1 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1219811-91:
(9*1)+(8*2)+(7*1)+(6*9)+(5*8)+(4*1)+(3*1)+(2*9)+(1*1)=152
152 % 10 = 2
So 1219811-91-2 is a valid CAS Registry Number.
