219954-12-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219954-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,5 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 219954-12:
(8*2)+(7*1)+(6*9)+(5*9)+(4*5)+(3*4)+(2*1)+(1*2)=158
158 % 10 = 8
So 219954-12-8 is a valid CAS Registry Number.
