119971-03-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119971-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,7 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119971-03:
(8*1)+(7*1)+(6*9)+(5*9)+(4*7)+(3*1)+(2*0)+(1*3)=148
148 % 10 = 8
So 119971-03-8 is a valid CAS Registry Number.
