370839-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 370839-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,0,8,3 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 370839-65:
(8*3)+(7*7)+(6*0)+(5*8)+(4*3)+(3*9)+(2*6)+(1*5)=169
169 % 10 = 9
So 370839-65-9 is a valid CAS Registry Number.
