1217519-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217519-96-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,5,1 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1217519-96:
(9*1)+(8*2)+(7*1)+(6*7)+(5*5)+(4*1)+(3*9)+(2*9)+(1*6)=154
154 % 10 = 4
So 1217519-96-4 is a valid CAS Registry Number.
