619-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 619-37-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 619-37:
(5*6)+(4*1)+(3*9)+(2*3)+(1*7)=74
74 % 10 = 4
So 619-37-4 is a valid CAS Registry Number.
