74782-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74782-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,8 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74782-22:
(7*7)+(6*4)+(5*7)+(4*8)+(3*2)+(2*2)+(1*2)=152
152 % 10 = 2
So 74782-22-2 is a valid CAS Registry Number.
