137378-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137378-76-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,7 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137378-76:
(8*1)+(7*3)+(6*7)+(5*3)+(4*7)+(3*8)+(2*7)+(1*6)=158
158 % 10 = 8
So 137378-76-8 is a valid CAS Registry Number.
