199464-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199464-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,4,6 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 199464-37:
(8*1)+(7*9)+(6*9)+(5*4)+(4*6)+(3*4)+(2*3)+(1*7)=194
194 % 10 = 4
So 199464-37-4 is a valid CAS Registry Number.
