157795-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157795-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,9 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157795-64:
(8*1)+(7*5)+(6*7)+(5*7)+(4*9)+(3*5)+(2*6)+(1*4)=187
187 % 10 = 7
So 157795-64-7 is a valid CAS Registry Number.
