951116-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 951116-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,1,1,1 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 951116-91:
(8*9)+(7*5)+(6*1)+(5*1)+(4*1)+(3*6)+(2*9)+(1*1)=159
159 % 10 = 9
So 951116-91-9 is a valid CAS Registry Number.

Converting 9-methyldipyrrinones to 9-H and 9-CHO dipyrrinones
Boiadjiev, Stefan E.,Lightner, David A.
, p. 8962 - 8976 (2008/02/10)
Yellow 9-methyldipyrrinones can be converted readily and in high yields to symmetric linear tetrapyrroles, blue biliverdinoids, which are cleaved in half, smoothly at room temperature to afford yellow 9-H dipyrrinones, and 9-CHO dipyrrinones as their viol
