37570-76-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37570-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,5,7 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 37570-76:
(7*3)+(6*7)+(5*5)+(4*7)+(3*0)+(2*7)+(1*6)=136
136 % 10 = 6
So 37570-76-6 is a valid CAS Registry Number.
