670749-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 670749-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,0,7,4 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 670749-33:
(8*6)+(7*7)+(6*0)+(5*7)+(4*4)+(3*9)+(2*3)+(1*3)=184
184 % 10 = 4
So 670749-33-4 is a valid CAS Registry Number.
